Which of these is likely to be more reliable: EVGA 550 B5, EVGA 650 B5, EVGA Supernova 650 GA, Asus TUF Gaming 550W? They're all in the same category. I only really need 450W so either of these is fine in that respect, all I really care about is it not blowing up. The prices are all pretty similar for me except the 550 B5 is a little cheaper than the others, so I'm leaning towards that one, but then again the GA and TUF have a double ball bearing fan which is neat.

Currently have Radeon HD6870, and I also have a pretty old CPU so it'd be great if I could use DX12/Vulkan...

Well, this is getting even weirder now. Booted into Win7 with 486FSB and 7x multiplier, same settings as last time, clock is running normally. Booted into Win10 with the same settings, and.. time is running normally too! Guess I'll see if it starts freaking out again or not..

I'll try it on W7 (dual boot here) and see if it's any different.

Hmm, do you think the speed-up issue happened because I raised the FSB too high? I didn't notice anything just raising it to 378, but maybe that just wasn't high enough for me to perceive it. I've seen people use pretty high FSB and low multiplier though and they never had this problem.. Maybe just a Windows 10 bug.

Anyone else ever had this problem?

Weird... I just tried 486 FSB and 7x multiplier, which still puts my CPU at 3.4GHz but lets me select a memory multiplier that matches one of the specifications listed in the SPD. Then I set the timings manually, and it seems all my memory errors are gone. I guess it was auto setting timings to the wrong thing? Oh well, I still had to revert to stock because of another problem.. everything ran too fast. If I looked at the clock in Windows it would go 1.5x faster than it normally should, and everything in games happened way too quickly. Any idea how to solve this? I tried bcdedit /set {current} useplatformclock Yes in CMD already, but that didn't help.

Hmm, this is brand new RAM though.. It's like a month old at best. I originally got more quality 1600Mhz sticks, but they ended up being incompatible with the board (memory chips themselves were too big in size for mobo to recognize) so I had to get these. Don't want to get new RAM again..

Hey guys, I'm back. I've been messing around with overclocking my CPU as you suggested, but have run into a bit of a problem - Prime95 is stable 4 hours at 3.4GHz and 1.35 Vcore, but I noticed my browser was crashing sometimes. Ran MemTest and found out that my memory is giving me errors! I was not expecting this at all since it's downclocked to 378Mhz as CPUz currently shows, since I didn't want it to affect stability while I was messing with the CPU clock. It's DDR3 rated to run at 667MHz (1333MHz actual), so I'm not sure why it's giving me errors. Should I try to boost the voltage? It's set to AUTO at the moment along with the timings. Specs for reference: Core 2 Duo E6850 3GHZ @ 3.4GHz Kingston 1333MHz DDR3 9-9-9-24 Asus P5Q3 Thanks for any help.

Haha yep, that's reassuring.. unless I do phase-change cooling or something I just thought that there was no way to change the memory speed at all on this motherboard.

Well, that's still pretty good I probably won't go over 400 because of temps. They are already close to 60 with Prime. (Then again, I think I installed the cooler backwards, it's working against the case fans lol.. gonna have to reinstall that when thermal paste gets here)

OK, thank you guys, I think I get it now Basically if I set "DRAM Frequency" in BIOS to 667, it will make the FSB:DRAM ratio 1:1, and that will let me overclock the CPU without running into memory limits.

Nvm, think I got it

But CPU-Z shows that the ratio is 1:2.. do you mean that I can change the ratio by adjusting the "DRAM Frequency" option in the BIOS? My bus speed is 333, so RAM is 666 or 1333 effective (the max it can do, going by spec). Also the timings are 9-9-9-24, is the 6-6-6-18 you suggested only for DDR2 or should I try that instead? (I've DDR3)

Hi guys, I'm planning to OC my core 2 duo, and I'm wondering, if I change the DRAM frequency manually in the BIOS, does that automatically change the FSB:DRAM divider? I have 1333MHz memory and the CPU has a 333MHz bus, which makes it a 1:2 ratio, as CPU-Z shows. I don't really want to OC the memory, so if I set it to a lower speed and then up the FSB, will it still stay in spec? Also, how do I find my stock VCore? It shows as different values depending on load in CPU-Z. Highest I've seen it is 1.264, so should I just set it to 1.25 and go from there?
