Posted March 30, 201411 yr ...It's a incredible frequency Do you have tested on air this cpu? Edited March 30, 201411 yr by ruggero
March 30, 201411 yr Author Ruggero, I've tested it on water only. 2900+ 1M with vcore < 2V. Valid 3000+. Ok,thank's and again congratulation for the score.
April 11, 201411 yr Did you forgot that nForce 2 chipset always works best with x-x-x-11 timings? both stability and performance IIRC. or maybe superPI is faster with 2-2-2-5 instead of 2-2-2-11?
April 11, 201411 yr No, I haven't forgot, but 2-2-2-5 is faster than 2-2-2-11 on my board/bios. Mine generally are also.
May 6, 201411 yr Nothing special - 1.85V or so. Don't remember exactly, but this particular board does not scale past 2V on the chipset.
May 6, 201411 yr Okay, thanks. I need >2.3v to go 240fsb 2-2-2 on A7n8x-e deluxe (2.0v - no go, only 230mhz 2-2-2) - it works fine in 1M but cannot complete 32m (dunno if this is overheating, missing 5V caps (desoldered them to mod different mobo) or memory - should check this today). My old result was commented by myself that I had used 2.48v vdd to go 250 2-2-2 and I'm not sure if this is clever/safe thing (I use stock radiator on NB).
May 6, 201411 yr Try with higher volts on the 3.3V rail. Modded bios is also very important, but I guess you're using one, since you're able to do 250MHz. You can also try L12 hardware mod. I haven't yet killed NF2 chipset with voltage, but if you're not cooling it fine, these volts won't help you. Generally speaking, my boards does not scale good with NB voltage. I have only one board that likes high volts and another one that can't complete 32M at 250MHz with more than 1.6V on the NB I've also had NF7 that can't do more than 250MHz for benches no matter volts/bios/cpu.
May 7, 201411 yr Thank you Ivan. I have resoldered caps, changed nb TIM and went to 3.7v - now everything is stable @252 2-2-2 but one of my winbond sticks suck - now i need to get my 2*256mb and 2*512mb winbonds sets back from friend and I'll be able to enter socket A competition.
May 7, 201411 yr There are plenty of PSU modding guides over the net, you can check x-bit's guide or get a PSU with adjustable rails. TerraRaptor, I've never went up to 3.7V. Edited May 7, 201411 yr by I.nfraR.ed
May 8, 201411 yr D3mox I had a standalone psu with 3.3v mod - just because overvolted 3.3 rail is not that good for other setups. It is also important to have a psu that is able to provide as much power as possible @3.3+5.0v rails (i.e. my current coolermaster 800w has 150w which leads to shutdowns of a7n8x @2ghz barton aircooled, my old huntkey was rated 180w and so was better).
