Rumman reacted to Zenedge in From a4tech n-70fx to logitech g102? Need suggestion
the g102 is a very good mouse for the price, has decent software(but GHUB could be improved) and it has a nice minimalistic look.
however, if you could spend abit more, then the g304 is a really really great mouse, it comes with the better HERO sensor, and its wireless too.
Rumman reacted to Applefreak in Modded GPU cooler
Just get 2 fans like 2 80 mm or 2 92 mm fans on there and you should be fine. The 1060 is not that power hungry to begin with. If you want to go a step further, Artic cooling has some nice GPU heatsinks available. They are somewhat price though and take up 3 slots. You can also use 120 mm fans if you want to, just make sure you can somehow mount them for good contact. You should be able to run them at 7V near silent without the need for a fan curve (which would require soldering them onto the original fan header on the pcb.
Rumman reacted to 191x7 in Next possible update?
Limit your budget to $20 up to $50 and don't even look above that for a cooler, it's not worth spending more for cooling a $150-$200 CPU.
Even a Snowman cooler from AliExpress ($18-$25) is plenty. That's the Cooler Master hyper 212 performance range.
The latest Scythe Mugen (5) would be a top choice.
Rumman reacted to mariushm in Low quality MB with VRM
It doesn't cause the CPU to heat more and the less clock boosting overhead is debatable.
The VRM (the circuit which converts 12v to the voltage the processor needs) can function up to a certain temperature, let's say 100 degrees Celsius.
Depending on how much power the processor consumes, this circuit will heat up more (because of losses due to efficiency).
If the processor overall doesn't consume a lot of power (which is the case for most 4 core cpus and some 6 core processors if you don't overclock them), this power consumption is low enough that the VRM doesn't reach that peak temperature ever.
With more power hungry processors, that peak temperature can occasionally be reached.
A processor doesn't consume a constant amount of power all the time, like for example a light bulb.
The processor automatically adjusts the frequency of each core as needed - if you have an application or game that uses mostly two cores, the processor will reduce the frequency of the other cores or even turn them off for short periods of time to save power.
So let's say you have a quad core processor like Ryzen 2200g or Ryzen 1400 which consumes around 40 watts at maximum 100% on all cores, but only 10-20 watts when idle (when you're watching movies, typing a comment on this forum and so on)
When idle, the VRM will slowly go up from around 25-30 degrees Celsius ambient temperature and will slowly go up to let's say 40-50 degrees Celsius and stay around that temperature (the heat is dissipated into the motherboard and is moved away by the cpu fan and other fans in your case)
When you start a game or some application that uses a lot of cpu power, your processor starts to consume 40 watts or so, and now the VRM starts to produce more heat. So, it will gradually go up in temperature and will probably stay at around 60-70 degrees.
A heatsink on the VRM will slow that gradual rise in temperature and will keep the temperature lower.
So for example, let's say with a quad core, it will take one minute for the VRM to reach 60-70 degrees in temperature and stabilize there. With a heatsink on the VRM, it may take up to 5-10 minutes to reach around 55-60 degrees Celsius.
Either way, the temperatures are well below that threshold of 90-100 degrees Celsius.
Now, let's repeat with an 8 core processor that consumes 100 watts when all cores are at 100%
When idle, same story, the cpu doesn't consume much.
When load, the temperature starts to rise up, and probably within a minute, you may reach 85-90 degrees Celsius. With a heatsink on the VRM, it may take 5-10 minutes to reach 90-100 degrees or the heatsink may actually be good enough to always keep the VRM below 90 degrees.
If the temperature goes above 90 degrees, the BIOS and the vrm controller detects that and sends a signal to the cpu : "Hey CPU, try to reduce your power consumption and give me a bit of time to cool down because I'm too hot"
So, now your CPU will throttle, it will reduce the frequency of some cores and will turbo boost less often or not at all in order to consume less power.
As the cpu demands less power, the VRM produces less heat, so it will gradually cool down... it may take a couple of minutes to go from 90 degrees Celsius to let's say 70 degrees Celsius.
At some point where the temperature is low enough, the bios or vrm controller may tell the CPU "ok, you can go nuts again and boost and go 100%, I'm cool enough"
With no heatsink or minimal heatsink, you'll soon notice kind of like a seesaw effect where the temperature of the vrm goes up and down a few degrees. If you're doing something heavy that keeps the cpu at 100%, you'll however notice that after some period, once that vrm high temperature is reached, the cpu will more or less stay with a bit of throttling, because the vrm heats up faster than it cools down, so it never gets a chance to cool down and stay below that temperature threshold.
So, the cpu will always throttle a bit, which means it will actually consume less power and therefore should actually be a bit cooler.
Rumman reacted to mariushm in Motherboard HWinfo questions
VRM = voltage regulator module.
There's a vrm controller chip (under the text that says VSOC in the picture below) which controls multiple groups of components that convert voltage from 12v to some lower voltage... think of these groups like cylinders in a car.
Each group has at least one hi side mosfet, one lo-side mosfet, at least one inductor and at least one capacitor. They work together to create the power the processor needs.
Hi-side mosfets , Lo-side mosfets (these can be combined into chips called power stages) , inductors (those gray/black squares) and capacitors (those round silver things closer to cpu socket)
Chipset creates more pci-e lanes, contains usb controllers and sata controller (System on chip part inside CPU also contains a sata controller and a usb controller for some usb ports that go on io shield)
Chipset also connects sound card, network card and other onboard stuff to the cpu.
Rumman reacted to Eigenvektor in Memory timings and speed
Some software may profit from the higher speed, other software may suffer from the increased latency. You can try to find a middle ground between higher frequency and lower latency.
Overall, I think your best bet would be to simply benchmark it. Check performance of games/software you use one way, then the other way. See how much of a difference it makes, if any. That should help you find the optimal setting for your system and use cases.
Rumman reacted to maartendc in PC parts Price hike due to Coronavirus
I don't know if this topic meets the requirements to be a "news thread". This seems more appropriate for the CPU subforum.
Anyway, price fluctuations on one single part could be due to many factors, local supply and demand for example. Unless we see a marked increase in all product segments, and across all regions, I doubt this has anything to do with the spread of the Coronavirus which originated in Wuhan, China.
Also, I think it takes a while for supply restraints to trickle down the supply chain to affect pricing. Most distributors have stock that lasts at least some weeks. Unless they are being predatory and "anticipating" a shortage and jacking up the price.. We saw the same thing when there was talk of Chinese tariffs impacting US pricing for electronics.. The tarrifs would likely be felt weeks, if not months after tariffs were imposed.
Rumman reacted to Metallus97 in AMD Motherboard
1. No, maybe besides IO performance and ability to reach fast RAM speeds. But general processing performance should be the same
2. Probably yes but it will still hold up for long enough, i guess. Just DONT OC anything and maybe try to undervolt a bit.
3. Having a bit of airflow over them wont hurt, but you shouldn’t be to concerned
4. Idd not run like a 3950x on that mobo
5. Make sure the BIOS is up to date. Otherwise your CPU wont be supported
Rumman reacted to jonnyGURU in Power outage, psu and pc components.
If you're using a quality PSU, there should be no impact to your hardware.
But nobody likes their PC shutting down on them in the middle of things. It's also not good for keeping your data free from corruption. So if you have a lot of power outages, you want to get a UPS.
