    That was a verified possible solution, but I installed the 23H2 again and I am re-doing the core OC. I must share here what I found so it can hopefully be useful.
     
    What caused the instability with the newer OS isn't a compatibility matter or being an engineering sample, but rather an updated way of how windows uses the CPU and the proper thing to blame here is my OC. the newer OS 23H2 could give lower CPU latency and higher memory bandwidth on Aida64 (about 1-7% improvements in each field) and even better single core performance (1-2% out of margin of error). being limited to 45W means the CPU won't boost enough to show off multi core instability. I used that to my advantage on older versions of windows to get higher performance on lighter workloads while staying stable on heavier workloads due to power limit. For why I am not increasing the power limit to 120W which should be fine for my motherboard is that this PC is running on battery power so efficiency matters a lot. The newer OS allowed the CPU to do better and boost better on the same power limit which in it's turn caused instability.
     
    This is the whole story I believe. It took some real time to verify and come up with all of that so I think I should share it to fill curiosities.
     
    Now I am just re-doing the core OC

    easy fix: install previous windows version.  you cant expect software being optimized for "engineering samples", especially not forever.

    When Speed Shift is enabled, use the Windows High Performance power plan. This automatically sets Speed Shift EPP to 0. This tells the CPU to run at full speed regardless of load. There should be no additional latency when you do this. The Balanced power plan will slow the CPU down when lightly loaded. This can increase latency. 
     
    It sounds like the turbo ratios in the FIVR window are causing the problem. Try pushing the Defaults button on the left bottom side of the FIVR window. This will try to read the default turbo ratios from the CPU. This should work with an ES processor.

    Your CPU supports Speed Shift Technology. Windows 11 23H2 seems to assume that if Speed Shift is available then the BIOS must have enabled it whether it is enabled or not. Try enabling Speed Shift in the BIOS and see if that makes any difference. 
     
    I would disable Windows 11 core isolation memory integrity and anything else VBS related. These features prevent software, including Windows 11, from reading information from your CPU. This might be why your CPU is not being setup correctly. If Windows 11 cannot read the turbo ratios that the BIOS has set then it might just set all turbo ratios to 51.

    After VBS is disabled, reboot and try running,
    ThrottleStop 9.6
    https://www.techpowerup.com/download/techpowerup-throttlestop/
     
    Post screenshots of the FIVR and TPL windows. The FIVR window will likely show that the staggered turbo ratios you set in the BIOS are not being used. If VBS is disabled, you should be able to use ThrottleStop to set the turbo ratios however you like. I am not sure if you can also do the same thing with Intel XTU. I do not know if XTU will properly support your ES processor. ThrottleStop should work OK.

    CAT5e ethernet cabling is generally much much better than what they will use for phone lines, it may help.
    Conductor size reduces attenuation (usually negligible difference in a house), the number of twists in the cable is what helps reduce noise.  Shielded cable might help, but you need a good ground at one end.

    Generally if you can move the cable even slightly further away from the mains cabling it may help and try to avoid it running parallel to the mains cabling if possible.

    Depending on where you live in the world it could be due to negligence on the ISP's part. I know many American telecoms have pretty much given up on copper. AT&T stopped selling ADSL service and Verizon has left its copper to rot and refuses to maintain it. If the issue is on the ISP's side there might not be much you can do. 
     
    Depending on how the ISP hooked up the service you might be able to eliminate your home wiring and test. I know a common thing in the US was to installed a NID on the side of the customers home. The NID would connect the ISP's wiring to the customers wiring. If you can gain access to the NID you might be able to disconnect the home wiring and test to see if the issue still persists. If the problem isnt present when you bypass you home wiring then you know its the wring in your home. If its still present then its the ISP's problem.

    Islam Ghunym reacted to PyCCo_TyPuCTo in All possible causes of CRC errors in ADSL connection   
    To answer your question CRCs increment when a corrupted packet is detected (and dropped). A ton of different things can corrupt a packet.
    You actually have really good SNR and attenuation values, unless these numbers fluctuate you should be good there. Are your CRCs intermittent or is it a slow trickle? If they come in in bunches, are you saturating your link during those time frames? Saturation will cause CRCs as well.
    Have you tried complaining to the ISP and have them run their checks remotely? There could be a bridge tap somewhere on the path between the CO and your home.
    They can also try and play with the DSL parameters to try and improve things, but that's granted they see something not quite right on their end, and actually care about doing something. I'd imagine residential DSL is not going to be looked at by higher tier technicians.

    Islam Ghunym reacted to RONOTHAN## in tweaking and power limits of a CPU   
    Uncore is the frequency at which the CPU can access the cache and other cores, it in itself shouldn't really affect power draw much, if at all. You can do a bit of testing, but unless you're raising voltages like the System Agent (what the Uncore runs on) the only power consumption increases will be from the CPU running more efficiently per clock which should be well under a watt at most.

    Islam Ghunym reacted to mariushm in Skyhawk VS Barracuda   
    access time is maximum time it would take for the read/write heads to be moved over a particular track, plus the time it takes for the data to arrive under the read/write head to be read.
    When the heads arrive over the track the whole track is read in drive's ram and what's not needed is dumped.
    If a file is not fragmented, then it's in continuous area of the platters (consecutive tracks) so once the first sector of that file is read then the drive can read tracks sequentially and give you the file at highest speed possible.
    If the file is fragmented, then drive has to read a track, then seek (move heads to) another track, wait until sectors with file data arrive under the heads then read the next fragment of the file and so on.

    In theory, being a "surveillance" series drive, the Skyhawk should have a firmware optimized for writing multiple files/streams in parallel and lower response times (well.. not really response, but it's hard to explain)
    The basic idea is that you may have 8-16 security cameras and the software records each camera at 5-10mbps (~ 1MB/s) and writes 8-16 files at 1 MB/s the drive is supposed to handle this much better than a regular drive and report to the software that the data was written much faster and therefore the software won't miss video frames because it's waiting for the drive to complete writing previous frames.
    In general such optimizations means you lose peak read/write speeds, drive won't be as fast as other drives with same rpm and platter density, but it's better suited for writing multiple things in parallel.
    Also in theory, some such series of surveillance/security drives (ex wd purple) claim they can tolerate higher temperature better - because those security camera recorders can often be locked in metal boxes with poor ventilation so the drives often run 24/7 writing stuff and also get much hotter.
    In practice I don't how much is true.
     
    Otherwise the rpm is not the only thing that matters. Drives can be made with different platters, which have different densities.
    For example, your 2 TB could have platters that an store 500 GB on one surface, so the drive is made with 2 plattes, using all four surfaces.
    The 4 TB could be made with newer platters that store data much densely, so for example they could do 800 GB per side ... so the 4 TB can be packed in 3 platters, using 5 surfaces.
    Because there's 3 platters, the access time may be higher (because you have more heads, more weight, so it takes a bit more to seek a track and move the whole assembly) but once the reading starts, in one rotation the drive reads more bytes from the disk, because the data is packed more densely.
     
    It also matters where a file is read from or written to. If you want exact numbers, use tools like HD Tune - HD Tune website - that reads drive surface from the first sector to the last and draws nice graph with the speed

    the faster spinning drive (7200) will be faster but if you have both these drives why not plug them in and bench them in crystal disk or something?

    Islam Ghunym reacted to Somerandomtechyboi in vcore/cache LLC   
    I use over decade old boards without llc since its either full llc or no llc which is pretty terrible
     
    No llc even with 0.08v vdroop is still better at oc from my experience vs llc, but this is decade old stuff, i think the standard for new stuff is to have some llc but not just full llc to the point that theres no vdroop, something to do with vrms but i forgot what, so vdroop to a volt is better than llcing to a volt
     
    awhile ago i was screwing around with my good sample pentium e5400 it can do 4.5g bench stable at 1.52v but when i enabled llc and set 1.52v yea didnt work and it just crashed as soon as i loaded the cpu, and this is on an asus p5q and asus are appaently known to have pretty good llc profile even on the older boards

    Islam Ghunym got a reaction from Kelp5127 in Studio Headphones vs Gaming Headphones for Gaming? Looking for Opinions.   
    If you want to hear footsteps properly you gonna need a good amplifier + a good software. The kind of hardware the headphone is not going to do much if anything for that. You gonna just hear more close to real sounds + more low and high frequency sounds. Footsteps, explosives or all other similar sound effects have really much higher frequency than being not present by any kind of headphone.
     
    On the other hand better headphone can give better sound staging more close to real and with that kind of vibrance footsteps would be more clear from which direction, but you can still determine where are these footsteps even with dump headsets with good software processing. It comes down to how good the game engine handle these 3D sound and output it properly to your headset so that you can easily determine these sounds and where they came from.
     
    It is all about software in the end + good amplifier for clear sounds while the premium sound staging is an additional very expensive and not a vital feature that helps you to win your games.

    Islam Ghunym reacted to Chiyawa in Ryzen automatically limiting power when temperatures goes beyond 73°   
    Hmm... Well, one way to elevate the restriction is to get a better cooler. PBO will deactivate if the temperature rise above 70c, though I'm not sure about this, but my Ryzen 3600 began to reduce the CPU clock little by little from all core 4100MHz to around 3900MHz while maintaining around 71c.
     
    I use Cooler Master Hyper 212 LED Turbo cooler for my CPU, and it took about more than 30 minutes of stress test to drop the frequency from 4.1GHz to 3.9GHz all cores. Maybe a better cooler can help?
