Zap, please post your impressions
I spent several hours on my two x58 setups today.
Step #1 swap out ES chips with retail chips (all are Core i7 965)
Step #2 break out with some fresh Patriot Viper 1600MHz RAM (3x 2GB)
(step #2.5 swap out one PSU because of a fan issue)
I must be doing something wrong because my two setups (one MSI Eclipse, one Intel DX58SO) won't go very high on the system bus. The MSI is also a bit flakey on the turbo mode implementation, with multipliers bouncing around a bit. The Intel is pretty stable when overclocking using the turbo mode. Got it up to a 29x multiplier (3.87GHz-ish) on stock cooler and it was fine using Prime95 until the CPU heated up (might be getting water cooler tomorrow).
Having a bit of problem with the memory. At stock speeds (1600MHz 9-9-9-24 1.65v) the MSI board was pretty unstable while the Intel board a lot more stable. Both boards, enabling XMP magically made it a wee bit more stable, the MSI much more so. Makes me wonder if the MSI board just throws more VDIMM into the mix. The Intel board has REALLY short traces for memory slots, unlike all other boards on the market. I'm betting that people will consistently get better memory clocks, lower memory voltages or lower latencies on the Intel board.
MSI board is on latest BIOS which enables 3 way SLI. I'll have to test that again tomorrow to see if it works properly and stably. Last time I tried it, machine kept crashing in 3D apps. However, found out later that memory was really unstable so that may have caused it.
Intel board will be flashed to latest BIOS tomorrow (right now says "evaluation" when POSTing 😛 ). Board does not support SLI. Strangely, Velocity Micro sells their "Edge" systems with the Intel board and has SLI as an option. Makes me wonder if 1) they use hacked drivers 2) they use hacked BIOS 3) they don't know that it doesn't work on Intel boards and will have unhappy customers.
So, can anyone give me a 2 minute explanation of how best to overclock Core i7 chips? 😕 Am I just being too conservative with voltages? Most I've gone is about 200mv over stock.
