Man... I want a Sandy Bridge system so bad, but there's no way I can justify it. I have a C2Q 9400 running at 3.6 GHz with 8 GB of DDR2 at 900MHz. All the games I play are GPU limited (4870). If I do upgrade, the CPU, mobo, and 8GB of RAM will all have to be replaced, and chances are I'll be getting... what? Maybe 4.5 GHz out of the 2500K? Sigh. Even with the IPC improvements it's still not really worthwhile. I miss the days when upgrading got you 500% extra performance instead of 50% extra. Edit: it also bothers me that the latency on DDR3 RAM is still pretty much the same (in terms of nanoseconds) as the DDR2 RAM I've been using for years. #$%@#$

I want the cheapest motherboard with: * x8/x8 PCIe slots. None of this stupid x16/x4 crap that some manufacturers are doing. * EFI * Not poo poo quality. I wonder if I can get a board like that for $100.

How far have people gotten their 2500Ks in terms of OCs? I'm running at 4.65GHz at 1.35 Vcore via a CoolerMaster Ultra 212+ on the el-cheapo Gigabyte P67A-UD3. It boots into Windows at 5 GHz on 1.4 Vcore, but crashes immediately afterwards. I don't think it's safe to bump the Vcore any higher, sigh.

Kashwashwa posted:This is the exact combination of CPU, mobo and Heatsink I just ordered, with approximately the results I was hoping for. Right now, I have: 4.75 GHz (101.1 BCLK * 47) VCore 1.37V in BIOS, 1.358 actual idle, 1.31 load QPI/Vtt 1.14V System Agent 1.155V PLL 1.88V Temps at 100% 60 C measured by the motherboard utility, 61/68/68/69 C measured by CoreTemp. Stable on OCCT for 2 hours now. If this stays stable, gonna try for 4.8 GHz at 1.38V. Not going to go higher than 1.385 V in the bios (which should equate to 1.375 V actual idle and 1.33 V load). Sigh... my dreams of 5.0 GHz... dashed. Oh well, not going to complain. It was $280 total at MC for the CPU + Mobo. This, plus the 2 5870s I got a month ago for $300 total, should last me a while. The only real complaint I have about the Gigabyte P67A-UD3 is that the PCIE slots are split 16x/4x, which is not optimal for Crossfile. But according to http://www.techpowerup.com/reviews/AMD/HD_5870_PCI-Express_Scaling/25.html , at 2560x1600, 8x/8x gives 98%/98% percent relative performance, while 16x/4x gives 100%/95%. I guess 4x PCIE 2.0 is good enough. Wedesdo fucked around with this message at 23:26 on Jan 10, 2011 |

Blah, can't get it stable at 4.8 GHz. Crashes after 30min - 1 hour on OCCT. So close, but I refuse to go higher than 1.4 Vcore. Need to play around with QPI/Vtt and VCCSA more. I think 4.8 GHz is doable < 1.4 Vcore, but I may just have to go back to 4.75.  4.8 sounds so much nicer!

Factory Factory posted:Yeah, that's pretty high. At 4.4 GHz, I idle at 35 and only get to 70 during stability burn-in, ~60 when doing Folding@Home. I heard that you should keep Vcore below 1.4V in the BIOS, which normally means less than 1.35V under load (due to Vdroop). These are 32nm CPUs, so they take less punishment than 45nm CPUs.

Okay, sticking with 4.7GHz at 1.375V. I guess it could be worse, but I'll have to wait for Ivy Bridge for 5 GHz.

bacon! posted:People have talked about memory prices dropping like rocks: I bought the 4GB kit version of this RAM and I wasn't impressed. The RAM needed 1.65V just to run at 1333MHz! At 1.5V this ram will only do 1066MHz. I really didn't want to go over 1.58V on my Sandy setup, so I eventually returned the RAM. I got some PNY 1333MHz RAM. Runs great at 1.5V, and will do 1600MHz at 1.58V.

LordOfThePants posted:One thing that is interesting is that while Real Temp is giving me temps of around 30° at idle, SpeedFan and the Gigabyte software are showing them around 16-17°C. I'm not sure why the values are different when they're supposed to be reading the same sensors. For me, the temperature on Core 0 is always a good 8-10 C lower than temps on Core 1 and 2. I think EasyTune reads the Core 0 temperature only. My theory? Core 0 is next to the unused (for us) graphics core, so it has a lot of excess silicon to spread the heat around, whereas Core 1 and 2 are surrounded by other heat-generating components.

The fix of course is a chipset redesign so you'd have to get a new mobo. I assume Intel will fund warranty replacements of affected boards.

Vermouth posted:i've had a really hard time getting a straight answer to this question, hopefully someone here can tell me - will a coolermaster 212+ fit on an asus p8p67 LE (with ram in a2/b2), or not? The good thing about the 212 is that you can move the fan up a little bit if the fan is blocking the RAM slots. I have a GA-P67A-UD3, which also puts the CPU socket close to the RAM slots, and my 212 works fine after a little fan position adjustment.

Just got my bugged Gigabyte P67A-UD3 upgraded to a B3 Asus P8P67 Pro. What a difference. 4.8 GHz stable on the Asus at the same voltage as 4.7 on the Gigabyte, and looks like there's plenty of room to go up. 5.0 GHz, here I come.

COCKMOUTH.GIF posted:One thing you have to watch out for if you're going to purchase a motherboard with an onboard Intel NIC is if it supports Jumbo Frames. A lot of Intel reference boards I've purchased have the onboard Intel NIC, but research/drivers have often revealed a lack of Jumbo Frame support. I had to purchase a PCI Express Intel NIC that had Jumbo Frame support because the DP45SG's onboard Gigabit NIC couldn't do it. Seems like the Sandy Bridge boards' Intel NICs support it fine. edit: intel specs http://ark.intel.com/Product.aspx?id=52963

Living in Korea and not being able to speak the language to talk to ASUS support means I'll be keeping it. At least until my company sends me a work laptop so I don't get caught without a VT-capable computer. I'm pretty sure if you email their headquarters they can help you figure something out.

Any one else have problems with S3 resume failing when overclocked? I have a 2500K on a P8P68 Pro running at 4.8 GHz at 1.375V. Completely stable (20 hours OCCT, etc.), SpeedStep/EIST works without a hitch, and the machine will suspend to ram OK, but will not resume (fans turn on, but screen stays blank). Any ideas?

If you are offline it'll revert back to the pre unlocked values until you can get back online. It still wouldn't stop a dedicated enough hacker. Spoof your own server or re-write the microcode. If this ever happens though I'm buying AMD again, no matter how much slower AMD is.

I'm running a 2500K @ 4.8 GHz right now (1.38 V) on a Coolermaster 212 Evo, and judging by the various reviews, 4.8 GHz is more-or-less impossible for Ivy without serious water cooling.
