Noxinite`s SuperPi - 32M score: 7min 19sec 313ms with a Pentium G3258



I managed to get 2800C6 (quite loose) to pass with non-wazza, but I couldn't get it to pass with wazza at all - even with +0.03V. Which is a bit odd as on air wazza barely needs more voltage than a basic 32M pass.



So my questions are:
1.) Does wazza capability decline past a certain point with temps even if basic 32M will still pass?
2.) Does wazza capability decline past a certain point with voltage even if basic 32M will still pass?
3.) Would colder IMC help with wazza capability?

Any help is appreciated guys.
To answer your questions:

Just because you can pass without wazza at said frequency/timings doesn't mean you will be able to pass with wazza with more cold or voltage.

It's best to find the max voltage you can run and pass with (usually 2.15v to 2.25v for me depending on the kit) and also the the exact temperature you need for your kit. This can be -125c to full pot depending on the kit.

Colder imc usually helps to a certain point, at least -60c to -125c should be a good range to try. Sometimes cold isn't necessarily better but in my experience 90% of the time it's better. Don't be afraid to blast cache voltage and core as well if your cpu needs it.

Pm me if you have any more questions and most important have fun

Thanks L0ud!

I tried again yesterday with cold 4770K and first boot 2800C6 tight passed at 2.3V, but for some reason it was single channel. Then it randomly started coming back and I was getting crashes at stock, so I had to stop the session.

CPU was -85 ish and ram was full pot.

Hey guys!

I know this topic is mostly about PSC, but when binning 2Gbit CFR, what formula should I follow? Either of the bios profiles is good for a start? TBH I dislike them, most are loose at some settings that makes binning with them useless, but I'm not too good with CFR yet.
I acquired 50 sticks of generic single sided 2Gbit CFR sticks, would like to bin them properly. I ran a few in a M5E with a good IMC 3770k, but only tried 2400C10-12-11. Best pair of 8 sticks I tried did spi32m at 1.62V at above speeds.

I think the highest spec for CFR was 1400MHz 11-14-14-35 @ 1.65V, so you could use this as a starting point for your binning.
Maybe [MENTION=17450]TaPaKaH[/MENTION] can also chime in.

Binning CFR is a waste of time. I had a special 2x4GB kit from G.Skill but even that could not compete with PSC or Samsung D-die. So you have no chance to find something actually useful on OEM.

CFR may be decent for a frequency run, but since there's also such a thing as mfr it's not nearly as useful anymore.
