What are the expectations for Evga SR2?
Are you asking if anyone has similar parts or experiences? I’ve owned one for a long time and recently messed with my OC profile, so I’ve been tweaking it lately. Everyone around me is showing off their impressive overclocks, which makes me puzzled about why mine isn’t improving. Right now I’m stable enough to run a couple of Cinebench tests at 4.53ghz with two x5680 chips, bclk at 183MHz, turbo off and speedstep disabled. I can’t push past 4.48, which feels like a tough limit. I managed 4.65ghz during a userbench run by just cranking it up, but the gains are minimal. I’ve changed RAM settings, tried different memory timings/multipliers, even adjusted voltage up to 1.5v and used Turboboost, but results aren’t much better. Are there any missing factors?
Photo of the ram just to pinpoint the correct ICs so you don’t mistake them and aren’t making mistakes because of incorrect BIOS settings. It would also be useful to see if pushing BCLK to its maximum helps. The value 182 seems low; increasing BCLK will likely improve performance. Have you tried pushing the core clock to its limit? Most should aim for 3900–4000 at 1.5–1.55V, but around 3800 is achievable with higher daily voltage like 1.45V (VTT).
It looks like Turbo Multi needs SpeedStep active for proper operation. In CPU-Z it only displayed the peak clock and around 2450MHz, which would change depending on load. The Task Manager didn’t show the actual speed. It’s not the RAM issue—I’ve checked with different sticks and even lower multi settings. I started this discussion because I’m struggling to get the base clock above 183, which is the maximum it should be. If the core is linked to the base clock, performance will drop at higher frequencies. I’ve lowered the core speed to match the CPU’s frequency and tried increasing VTT, but it stops at around 1.45V.
Interesting, I’ll give it a shot. It should definitely not be FSB or memory-related.
It seems the design will likely lean toward FSB, though CPU speed might not be the main factor. The 1366 variants differ a lot based on v-core and clock adjustments. I can estimate that a 5GHz setup would need a cooled water loop and around 1.60v-core for most models. Aiming for 4.6GHz is reasonable with good cooling. Honestly, I wouldn't expect much higher performance.
It handled 4800 at 1.6v with a lot of heat. The temperatures stayed manageable. Adjustments ranged from 4.0 to 4.8 with similar settings. It resisted certain voltage/clock pairings, so having adaptable RAM like Hypers was useful.
