K404 Posted May 19, 2011 Share Posted May 19, 2011 If Droop is bad, then to avoid OVP you will end up with a voltage that's too low to make 8GHz easy. If the characteristics are like my P5B-D, there will be a vCore startup spike thats higher than the windows vCore. Try without and see how it goes..... only one way to find out Hopefully soon I will be chasing CPU-Z again too Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted May 19, 2011 Author Share Posted May 19, 2011 ^^ Actually I sorted/binned 4 Cadars Mills from 37. These do ~5.4-5.6 GHz on air with 1.6v. the other ones were often 5.2GHz only. Let's hope one is good Quote Link to comment Share on other sites More sharing options...
Eeky NoX Posted May 19, 2011 Share Posted May 19, 2011 I'm not a specialist ofc, but pretesting on air doesn't really mean near nothing expecting very high freq under LN² Maybe a 5,2 will react differently with a higher range of vCore...

TaPaKaH Posted May 20, 2011 Share Posted May 20, 2011 Christian, you may have been a bit overkill on the Vcore, most chips don't scale past 1.5V on air. But anyway, 5400-5600 is very nice on air, expect those chips to be very nice on LN2 unless you hit coldbugs or FSB walls 5200 air isn't bad too Do you mind sharing your test results? (batch/pcb/clocks) I'm not a specialist ofc, but pretesting on air doesn't really mean near nothing expecting very high freq under LN² Maybe a 5,2 will react differently with a higher range of vCore... If it can't do 5000/1.45V suicide on air, then there's NO WAY it's an 8G chip ... air pretesting helps to get rid of the crap first so that you don't end up testing 30+ chips on LN2 with half stopping under 7GHz.

Christian Ney Posted May 20, 2011 Author Share Posted May 20, 2011 (edited) Unfortunately on my sheets when a CPU did best than another I overwrite the previous one with the best one . But here is what I have atm: P4 631 SL94Y : 3610A742 : 5.2 GHz 1.6v P4 631 SL94Y : 3610A742 : 5.325 GHz 1.6v / 7.2 GHz 1.8v -138°C (was out of LN2, today I will give him -196 ) CD 360 AL9KK : L645G598 : 5.6 GHz 1.6v CD 360 AL9KK : L645G598 : 5.5 GHz 1.6v CD 352 SL96P : 5634B265 : 5.38 GHz 1.6v CD 352 SL96P : 5634B265 : 5.2 GHz 1.6v / 7.2 GHz 1.7v -196°C CD 347 SL9KN : L540A636 : 5.0 GHz 1.6v So the worst one are missed -.- and sold or on a box named ''dirty CPUs'' I have to check if I kept an older sheet somewhere on a USB Stick btw: with pcb you mean A0109 for exemple ?

TaPaKaH Posted May 20, 2011 Share Posted May 20, 2011 Don't expect much out of those P4 - I had similar air clocking ones, under LN2 they ranged from 6.8 to 7.7GHz. C360s are looking interesting, I never had good clocking air samples from that model. 5634B is a "too late" batch for a C1, all 5634B C1 i ever had sucked, however Gautam managed to get one to 7.6 347 you may have a typo there, most likely it's an L740... Most malay from 2007 and newer are very consistent, 5000-5200 on air, 7400-7600 LN2. Almost not interesting to bin btw: with pcb you mean A0109 for exemple ?yes, but I'd like both lines of the PCB texts Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted May 20, 2011 Author Share Posted May 20, 2011 ok thx for the info, I will check the typo and pcb when I will be back home, now I am in the bus go take LN2 Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted May 20, 2011 Author Share Posted May 20, 2011 So I have 20L of LN2 for today. P4 631 SL94Y : 3610A742 : dunno : 5.2 GHz 1.6v P4 631 SL94Y : 3610A742 : 35608442-A0646 :5.325 GHz 1.6v / 7.2 GHz 1.8v -138°C (was out of LN2, today I will give him -196 ) CD 360 AL9KK : L645G598 : 35709271-A1858 : 5.6 GHz 1.6v CD 360 AL9KK : L645G598 : dunno : 5.5 GHz 1.6v CD 352 SL96P : 5634B265 : dunno : 5.38 GHz 1.6v CD 352 SL96P : 5634B265 : 35634284-A1014 : 5.2 GHz 1.6v / 7.2 GHz 1.7v -196°C CD 347 SL9KN : 5651B062 : 2L70132-6A1286 : 5.0 GHz 1.6v Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted May 20, 2011 Author Share Posted May 20, 2011 Sam, what cpu pll voltage for cedal mills ? atm 7.66 GHz 1.9v -170°C Quote Link to comment Share on other sites More sharing options...
TaPaKaH Posted May 20, 2011 Share Posted May 20, 2011 in general case - PLL doesn't affect anything, nor does VTT Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted June 2, 2011 Author Share Posted June 2, 2011 vmod done... I think Dunno if it works, I found too many way to do the vmod, I chose this one -.- Quote Link to comment Share on other sites More sharing options...
