J-bin 5960X here, caps at 4.8GHz all-core, 4.9 with HT off. Won't go above that even bench stable at the highest voltages that'd actually be dailyable (2.1v input voltage, 1.35v vCore). I'm also on 2x 360mm slim rads (Nemesis GTS Stealths) with 6x Noctua NF-F12 iPPC fans, with those slapped to max this CPU will still get pretty dang toasty at 1.35v. I daily it at 4.7/1.3v and temps are much better. 

Apparently Ring OCing is more important than pure clock though, I've heard from more experienced overclockers that 4.4/4.4 core/ring will actually perf better than a higher core clock, performance scales worse and worse after 4.5Ghz core. I currently run 4.7/3.7 core/ring, haven't had time to test dropping core and seeing if ring will go any higher. 

ring/cache/uncore OC will increase your memory speeds and decrease latency. But some people say it also increases the risk to bricking a CPU. So If you do increase OC uncore, don't go too high on the voltage. 

 

post up an aida64 brechmark of your ram speeds.

On X99 it doesn't actually touch RAM speeds, I'm running 3.7 (which is the wall stock, need OC socket or a hardware hard/softmod to get over that) which is higher than stock, and my RAM still runs the same speed. 

On X58 it does affect it, BLCK, Uncore, and RAM speed are all linked. IDK about X79, but I should have some soon (X79 Dark + 4930K + 4x4GB RAM, buying next payday). 
 

This is the best I have, just ran at stock XMP, I'll be getting the full version of AIDA64 once I have the mons as well:

your speeds are very poor. 

 

change the multiper to 2666 and rerun the test. This is my sticks, adjusting only primary timings. OC'd uncore to 4GHz (3000MB/s read speed gain). I could get more performance if I fix the tertiary timings.

at 2667, we want around, 77,000 MB/s (90% of 85,312 MB/s MAX)

at 3200, we want around. 92,000 MB/s (90% of 102,400 MB/s MAX)

Directly from HWBot's Article:

"A lot of boards out there seem to have a wall at around 3600 MHz to 3700 MHz. To bypass this wall we have to get the both supply voltages to the same level. So just connect both pins on the CPU which will result in a voltage of about 1,260 Volt. This should be fine for 4000 to 4100 MHz according to my testing." (emphasis added)

 

I hit an absolute, rock solid, impassible wall at 3700Mhz uncore on my EVGA X99 Classified. To get past that I'd need to pull the CPU and solder/otherwise connect two pins on the CPU.

What exactly is the point of making my RAM run slower? Lowering latencies makes sense, but bringing down the speed, why exactly? Again, if my uncore won't clock any higher, what's the benefit?

[GrockleTD]

@Zando Bob when looking at this page, recall my max cinebench score was 1316

timings affect both speed and latency. 

 

because your motherboard might be relaxing the tertiary timings too much. You might want to lock in the tert. timings at 2666 and than change back the speed to 3200.

I'd wager there is a lot more historical data on X58 with R15-- I'd suggest running both to check.

 

I can try to install and run R20 tonight. R15 I posted a few times in this thread, though I think a bunch of us crossposted to the cinebench main thread? IIRC there's a google doc to look up results by processor.

^^^ Good point, and the main benefits on CB20 are higher than 256 thread support (nothing on LGA1366 touches this) and AVX instructions (LGA1366 chips don't even support these). So for X58, not much point unless comparing to new CPUs.

I was under the impression that increased memory was part of r20? I could be wrong

It uses more ram sure, but that's purely because it renders a larger and more intensive scene. And it does that in order to slow down faster processors, since higher core counts absolutely blasted through R15. 

Cinebench has never been a RAM benchmark AFAIK.

I was more so meaning that increased memory bandwidth had more of an effect vs r15, although thinking about it recent experience would prove otherwise

Yea, I saw zero repeatable change in score as a function of ram speed. Any difference from 1033 up to 2000ish (in triple channel) was within run-to-run variation.

 

Uncore, different story. Ram speed itself, not a factor for cinebench R15 specifically IME.

[r2724r16]

I was able to buy an X58 system for C$120 with an i7 950, 10GB of RAM, a Gigabyte GA X58A UD3R, some Radeon graphics card, and a decent Corsair case (don't know the exact model). It's just missing a PSU and storage. I'll post pictures later.

 

I'm planning on turning it into a hackintosh (hopefully).

[Zando_]

Reminder that the SR-2 is stupidly thicc:

And I still need to get mine working reeeeeeeeeeeeeeeeeeeeeeeee but first I need a case to actually hold the damn thing. 

Also may we get an F in the chat for this Sabertooth: 

Couple mosfets cooked themselves (PQ117 for sure, PQ120 and the one to its left already had that bluing when I got the board so they may have already been toast). May try fixing it sometime in the future, it is only $10 or so for 10 of these suckers and I already have a soldering iron (would need a desoldering wick or whatever tho). If traces aren't damaged apparently it'll still work.

Is it a decent upgrade to go from a i7 920 to a i7 990x? Im doing it because of the lga 1366 socket.

Hell fuckin yeah my dood. 32nm Hexacores are a massive upgrade from the quads, especially the i7 920. 

You should be able to update your BIOS and then run Westmere-EP hexacore Xeons though. Which are the same thing as the i7s (32nm 6c/12t lads) but usually cheaper because there's more of them on the market. The X5670/X5675 are usually the best combo of price vs performance and OCing capabilities. These chips can swallow masses of voltage without issue and usually OC well, so if you have a reasonable cooler you should be able to daily 4.2-4.5Ghz all core. 

[Kilrah]

Still have my i7-970 build from 2010, running at 4.2 all core. Mobo is slightly flaky and sometimes hangs at boot, but when it boots it runs fine. It still gets some use occasionnally, including gaming, packs a very decent punch and was still pretty competitive even a couple of years ago.

Mine's in the mail. I haven't settled on a case either. The Anidees looks super promising (the 'Pro' variant is intriguing but I can't find any information on real-world use. The marketing copy impilies 3x radiator support....), buuuut my local computer parts store has a NOS Corsair 900D for a damn good price, and it'll also fit dual 480s and maybe another 240 or more. Downside is the 900D doesn't allow you to hide drives AND support radiators which visually bothers me. Probably moddable though.

I might need to do something like this on a Supermicro board I've got my eye on, as it's failing to post apparently. How did you go about finding the replacement chip?

I googled the number on the top lol, seems to be a standard mosfet that's quite cheap. Assuming it didn't burn out any internal traces, I should be able to just desolder the old ones and stick new ones on, tho my questionable (aka nonexistent) soldering skills may make that difficult if i do decide to attempt it.

900D supports HPTX as well? Oooooo it is a bigboye: https://www.corsair.com/us/en/Categories/Products/Cases/Obsidian-Series™-900D-Super-Tower-Case/p/CC-9011022-WW#tab-overview

Not a glass box like the Anidees is either (glass is nice but the Anidees is a lot of glass).

Yea! HPTX and XL-ATX support out of the box. Removable drive cages is a nice touch, 5.25 bays that can apparently be un-riveted. Dual PSU support, though at cost of radiator size.

 

I'm tempted to pick it up assuming it's not missing all the pieces and internal bits I'd need to assemble stuff. Doubly so if someone online has managed to install a bunch of rads and also kept the drive cages. I don't need server level drive cages but some would be nice.

tbh for an SR-2 a single 360 for the two CPUs would be plenty unless you really, really wanna push clocks. I'd slap 1.45v through my X5670 on a single slim 360 and it wouldn't break the high 60s.

Definitely true-- my x5675 is on a single 240 AIO and is rock solid. I'm thinking overkill for 2xCPU, chipset, plus potentially 4x GPU if i can get VMs to work. Probably won't need dual 480s for that even still, but......why not? haha.
