Intel E7*** 45nm Club - Page 8

post #71 of 323
Im running 3.2Ghz 400FSB x 8.0 at 1.325V. Idle 42 Load 60

Seems stable enough to run Crysis, High detail 1440 x 900 for 6 hours. (have not played longer than that and though there are few crashes in between which i believe was because of my unstable GPU oc-ed settings which i've already corrected.)

Im trying 3.6Ghz 400x9.0 at 1.325V now though

Try 400 x 9.5 with 1.34Vcore

I run @ 3.8 fine mate. How old is your chips may I ask?

I bought it for 3weeks only i think. Hm.. because of the country im in, im afraid my cpu may run too hot S: but i'll try

My E7200 results so far:

4.009GHz (422 x 9.5) @ 1.46V (CPU-Z, idle) passing Orthos Blend for 24 hours with RealTemp readings of 26C min / 74C max temp. Before the 24-hour run, Orthos small and large FFTs also passed for 3 hours each. I know this is pushing it, but Intel's 1.45V max spec on this processor has been broadly and fairly challenged among overclockers (Google "wolfdale 1.4v myth") and because my temps were okay I went ahead. Orthos Blend varies in its power damands and the 74C max temp was only intermittently hit. By contrast, I ran the Crysis Benchmark utility, an excellent surrogate for intense game play, in a 50-pass loop (in search of max stable overclock on my 8800GT) and the CPU only hit ~57C. That said, because my comfort level with current Intel processors is low 70s peak in Orthos and I don't particularly like pushing Intel's specified limits, I'm not yet entirely comfortable with this overclock. (Of course, my Nforce motherboard is no where near as good an Intel for overclocking and by my research an Intel should hit 4GHz with around 1.36V.)

An alternative I'm currently testing:

3.8GHz (400 x 9.5) @ 1.36V (CPU-Z, idle) is now running Orthos Blend in its sixth hour and the temp has not exceeded 65C. Because 3.8GHz benchmarks 3DMark06 in my rig only 125 points less than 4GHz does, I may well decide to keep it there as my final 24/7 choice. Haven't decided yet. (Again, an Intel based board would hit 3.8GHz with lower voltage.)

A note on my low-end HSF setup. Yea, I'm thrifty, but not stupid. The E7200 replaced an E4500, which had a heat sink twice as thick as the one included with the new processor, so I kept it. But there's a trick I've employed for a number of years with AMD and Intel stock HSFs. I use a Zalman fan bracket to mount a low-RPM 120mm fan an inch or two above the stock setup. (The initial idea was to be able to slow/quiet down the small high pitched HSFs while maintaining cooling in "silent" PCs.) Because it is larger in diameter it helps to keep the hot air exhausted at the base of the heat sink from feeding right back into the fan supplying it, greatly increasing the HSF's efficiency, and as a bonus it cools the NB heat sink as well. It's not better than the best of the aftermarket HSFs, of course, but it's as good as all but a few at significantly decreasing temps over stock. And you're out ~$10.

Got a question. How you guys get such firm bus speed and FSB? Mine are like 400.5, 1601.8 etc.

Mine seems stable enough to run kane's wrath(yet to try others) at 3.6ghz 400x9.0 1.325v.

i get blue screen whenever i try 3.8 400x9.5 at 1.34v o.O

It might be your chip.
Try upping your NB voltage!

The max Vcore is 1.3625 never exceed that or you run the risk of frying your CPU.

NYM
I notice you are running with a CM Hyper 212 try re sitting it with AS5 or Tunqi TX does it use a bolt thur kit. If not i would recommend buying one they are more secure and you can apply more force for better contact between cpu and heatsink

Try 3.6 stabel first then 3.8
