Crew Vivi Posted June 30, 2013 Crew Share Posted June 30, 2013 hey guys, many of you talk about a FIVR issue that some of the mobo brands have, what exactly happens when a cpu has this issue? like what is the symptoms, what happens when you run High Volt on maximus vs High Volt on gigabyte, does the CPU shut down or cant the board set the volts or what cool Quote Link to comment Share on other sites More sharing options...
Atlas Rush Posted June 30, 2013 Share Posted June 30, 2013 'till now I used 3 mainboards: 2 Gigabyte and 1 ASRock, no problems on any of them, even with premature bios, this week I'll get a Maximus VI Hero (my main mobo) and I'll give you a shout about that if I ever have any problem!

rsnubje Posted July 1, 2013 Share Posted July 1, 2013 hey guys, many of you talk about a FIVR issue that some of the mobo brands have, what exactly happens when a cpu has this issue? like what is the symptoms, what happens when you run High Volt on maximus vs High Volt on gigabyte, does the CPU shut down or cant the board set the volts or what cool I'm guessing they are talking about ES cpu's that have this problem. When you set for example 1.8v in bios, it's 1.6v real. On some boards you don't have this problem as it seems. Not all ES cpu's have this problem. The early ones mostly do.

Massman Posted July 1, 2013 Author Share Posted July 1, 2013 hey guys, many of you talk about a FIVR issue that some of the mobo brands have, what exactly happens when a cpu has this issue? like what is the symptoms, what happens when you run High Volt on maximus vs High Volt on gigabyte, does the CPU shut down or cant the board set the volts or what cool No matter what voltage you set in the BIOS, anything >1.6V will be 1.6V real. Your OC sense will make you say "this CPU doesn't scale with volts". Quote Link to comment Share on other sites More sharing options...
Atlas Rush Posted July 1, 2013 Share Posted July 1, 2013 http://valid.canardpc.com/show_oc.php?id=2850331 This CPU is so funny 5.2GHz validate 4C8T Quote Link to comment Share on other sites More sharing options...

Atlas Rush Posted July 2, 2013 Share Posted July 2, 2013 pfft, it's just a validate, on air, many people are better, many CPUs are better But I'm having fun with this system, it didn't happen for too long Quote Link to comment Share on other sites More sharing options...
xxbassplayerxx Posted July 2, 2013 Share Posted July 2, 2013 Even just as a validation... that's what... a 1.30V 5GHz 32M chip? Mine needs 1.475V to do 32M. Quote Link to comment Share on other sites More sharing options...
Atlas Rush Posted July 2, 2013 Share Posted July 2, 2013 There's who's been telling me that a CPU like this is wasted in my hands, since I don't freeze it, so it could be the luckiest CPU around, but still, it's useless. So, I just have fun, ignoring what the others say Quote Link to comment Share on other sites More sharing options...
K404 Posted July 3, 2013 Share Posted July 3, 2013 (edited) L310B488 2C/2T. 4.9GHz 32M @ 1.375v. 5.0GHz = BSOD Edited July 3, 2013 by K404 Quote Link to comment Share on other sites More sharing options...
Crew Vivi Posted July 3, 2013 Crew Share Posted July 3, 2013 (edited) L310B488 2C/2T. 4.8GHz 32M @ 1.375v. 4.9GHz = BSOD i tested 5 of those and drweez tested 2, they we've had from 1.5+v for 5ghz and as low as my golden 1.25v for 5ghz. all did the same -122 ish CB. EXCEPT for my golden 1.25v 5ghz does -100 cb so it sucks.. maxed 6.2 for pifast and my best L310B488 does 1.38v 5ghz and max 6377 pifast 6ghz cinebench -125. So after air binning ln2 binning is needed for sure . Low volts is good, but if it has CB too soon you will get scorned like me >_<. PS: what VCCIN / VRIN you using for your runs there k404?

K404 Posted July 3, 2013 Share Posted July 3, 2013 Hey Vivi I airtest at 1.85vRIN. At this load, I don't think PWM is any kind of bottleneck. Hell... My board doesn't even have it's PWM heatsink on it, the PWM is cool to the touch. There's enough correlation between MHz & volts that I can writeoff everything that needs >1.40v for 5GHz. I'm not in a position to LN2 test everything Quote Link to comment Share on other sites More sharing options...

I'm not in a position to LN2 test everything just for shits and giggles try 2.2v VRin for your 1.4 run and see if its 4.9 stable? Just so i can writeoff in my head that 2.2 is needed for 1.4 to be stable on my side, i know its high but for me this batch likes it high. we all still learning so it will help for me to know if it helps you or not Quote Link to comment Share on other sites More sharing options...
K404 Posted July 3, 2013 Share Posted July 3, 2013 (edited) Sure, give me 30 minutes (I know... it doesn't take that long, but i'm chilled) Done! 2.20vRin didn't help at all. I started at 1.60vRin and worked up, made no difference at all to MHz. I *did* notice that at low vRin, it was hard to get into BIOS to change settings- it kept freezing, even though it would boot and run SPi no problem I missed one BIOS setting before, this chip is 4.9GHz @ 1.375.

Atlas Rush Posted July 3, 2013 Share Posted July 3, 2013 Any tip for BCLK clocking? I'd like to check what's the maximum it can go with this CPU, atm I got 180MHz validate, can't go any further without fine tuning I suppose.. Quote Link to comment Share on other sites More sharing options...

Calathea Posted July 3, 2013 Share Posted July 3, 2013 ^looks really good. My chip needs 1.75 volt and -55 for that freq. Quote Link to comment Share on other sites More sharing options...

Calathea Posted July 5, 2013 Share Posted July 5, 2013 feel sorry for you bro. I don't think it's time to start bin haswell yet, waiting for better batches. Quote Link to comment Share on other sites More sharing options...
K404 Posted July 5, 2013 Share Posted July 5, 2013 Yea, I am done with binning until i've sold these rejects. I've had more luck with 4670K anyway. 3D06 is the only thing to really be affected.... and wPrime I suppose. Quote Link to comment Share on other sites More sharing options...
