OC X58 Xeon x5670 model - mounting at 3.91mm
Hello, so this is my config: Xeon x5670 Gigabyte GA-X58A-UD3R rev 1.0 with the newest bios 3x 4GB Kingston HyperX HKX1600C10D3/8G tripple channel I recently put my hands on this whole setup (with memory) as i brough it all for like $160 so the price to performance ratio was too good to ignore it. As far i managed to OC it to 3.91 GHz with all power saving features enabled. But the voltage... to make it stable i had to use 1.3 cpu vcore which seems high, i heard 1.3v is the maximum "safe" voltage on this chip, because the "voltage spike" might occur and increase the voltage up to +0.05v, and any voltage above 1.35v is dangerous to this chip (intel specs). Anyway, i dont think that too low voltage is the issue. Temps are quite ok, from 34-40 when completely idle, from 40-50 when doing light tasks like watching youtube + browsing web + few other light apps, to 70-75 on hottest core when stresstesting. I tried to lower the multiplier to 20 and setting blck to 200 and memory multiplier to make it round 1600 with all stock latency etc to be sure memory is not the problem - it didnt even post, had to reset the cmos. I tried to downclock the memory with my current 22x multiplier to be as close to/bit lower than stock 1600 and setting latencies on stock - still if I'm getting above 3.91 its not stable, no matter what. Any magic trick that i missed? Anyone had similar setup and managed to solve similar issue? I heard 4.0 GHz oc is easy even on x5650, so i was hoping for, like 4.2 on my x5670 but cant get past 3.91 :c Full config on the screens
I’m working with an X5675 at 4.5GHz (215x21) on a UD3R motherboard (Rev 2.0). I suspect the voltage is around 1.4V, but it’s been a while. First, set the BCLK to its default level, then disable turbo boost and all power-saving settings. Next, adjust your CPU and memory multipliers to low values. Gradually increase BCLK in 10 MHz steps while keeping the multipliers low. Perform a stress test (Prime95 or Intel burn test) after each adjustment. If it succeeds, raise BCLK another 10; if not, increment QPI/VTT voltage slightly but stay below 1.35V. Your board has held up to 220 BCLK, so aiming for 215 is feasible. Be mindful of frequency mismatches—some BCLK ranges won’t work, so adjust accordingly. Once stable, maintain low multipliers and run the test again. After confirming stability, lower memory and CPU multipliers, then stress-test for an extended period. Then fine-tune your memory settings (e.g., 1600MHz RAM with a 200BCLK should use multiplier 8). Continue testing. This methodical approach is outlined in this helpful guide: http://www.techreaction.net/2010/09/07/3...-gulftown/. Keep detailed notes in an Excel sheet to track what works. Remember, your Xeon might have missed the silicon lottery—replacement parts are cheap (~$40 on eBay), so it’s not a major concern.
Hello, your motherboard uses the Gigabyte GA-EX58-UD3R rev 1.6 BIOS and the X5675 CPU. It seems the CPU isn't working properly. You've tried updating the BIOS via Q-Flash but it didn't succeed. You mentioned Windows might work, but you're unsure about using FLASHSPI.EXE since your system is 64-bit. Your main questions are: Can the X5675 CPU run with this BIOS version? And how can you upgrade the BIOS from 1MB to 2MB?
