[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 881

post #8801 of 12379
I'm having a strange issue. I have a Gigabyte EP45-UD3L with an E5450 that I just installed, and Windows 8.1 won't boot. This install worked just fine hours ago (had a C2D E5200 in it). It always starts up with "Preparing Automatic Repair" and I managed to catch it giving an "Error Code: 0x000000C4" before automatically rebooting. I just tested and have the same issue with a Windows 8.1 installer USB drive, however a Hiren's Boot CD XP install boots just fine.

Try running Memtest to see if your ram is stable. Ram can cause all kinds of problems and symptoms can be intermittent.

Performance question for all of you with overclockocked quads (12mb cache). How many fps do you get in cs go all at low @1080p, and with which gpu card.

I presume some of you must have cs go installed.

Apparently I had flashed the wrong BIOS (thought it had microcodes modded in). It's working fine now with a proper modded BIOS. thumb.gif

If I had seen your post earlier I would have replied with the answer you found for yourself. I did this mod on my UD3P with no modded BIOS but I used a X5460, I guess that's not the case with E5450 though.

hey guys, i'm ending up upgraded my system to x5470 paired with P5Q3, will it boot if i try to stick 16gb kit of corsair CMZ16GX3M4A1600C9B or maybe higher speed if any suggestions.. and for additions, i'm really surprised asus P5G41T-M LX3 can keep up with x5470, this is just for testing anyway, with onboard intel gpu i can smoothly play 1080p on youtube, hehehe. thumb.gif

P5Q3 supports 1600(1800 OC) so yeah you should be fine.

My system is:

X5470 @4ghz
Asus P5k deluxe
8gb ddr2 800
GTX 960

I get 140-200fps in CS:GO @1080p with pretty much all gfx options maxed (4xMSAA). Suspect much higher fps with low gfx options.

Looking for some feedback on my overclock for an E5450 on a Gigabyte EP45-UD3L. It's currently at 424*9 = 3.81GHz at 1.275v in BIOS with 1:1 FSB:RAM and timings 5-5-5-15 (2x 2GB G.Skill DDR2-800 1.8v sticks at 1.9v). I got an error in prime when I tried FSB 434 (3.9GHz.) with all other settings the same.

Am I thermally limited yet? I'm not really sure whether to believe these temperatures or which program - what is the Tj max for these CPUs? Do you think it's necessary yet to mess with voltages other than vCore? Obviously, I don't want to increase any voltages if I'm at a thermal limit.

That's very tight memory timings so you will probably want to keep your memory at conservative speeds/timing until you dial in your max CPU overclock. Trying to O/C with tight memory timings and/or high memory speeds will preset a significantly higher challenge to O/C your CPU and reach stability especially with higher bus speeds. I would ONLY attempt to improve memory performance as the VERY LAST step in tweaking your overall system. You may need to go back and re-run that same test that failed but with your memory at more conservative settings (AUTO for memory, view the values chosen by AUTO and then manually set those same values for memory to give you a good place to start). Run MEMTESTx86 from a bootable USB drive and verify your memory is stable as 1st step.

As far as messing with other voltages besides vCORE, absolutely if you are looking to push your bus speed up (I don't know P45 specifically but I suspect this is true for all S775 chipsets with a north-bridge. I have to adjust just about every voltage in my system to reach my 4.65Ghz "24/7" O/C (this is a 1825Mhz bus). I could share what I use for BIOS settings but I have 790i chipset and will be different from your P45.

You indeed do not have much thermal headroom right now but that is probably not your limitation YET if you haven't messed with other voltages (however I think you are VERY close to your thermal limit). 80C is probably the most you'll want to get as a max temp under high stress (looks like you are on AIR) but 70's is better. I don't really think you are going to be able to go too much higher without a water block but I would suspect you could get closer to 4Ghz with some additional tweaking (you have a 9x multi and room to raise bus speed). According to Core temp the TjMax = 100C for both of our CPUs (I have X5470). I'm not going to test that limit and find out tongue.gif but I can tell you that at least for me, 85C hasn't showed to be a "problem" it is just about as high as I'm willing to take my CPU. As a general rule of thumb I would say that 80C as your max is safer. That's a full 20C delta from TjMax.
