EVGA 750i FTW Overclock Thread

[Eastrider]

Just a detail: **** your temps. When I saw it, I inmediately decided to finally buy the DTek Fuzion V2 block. Seems to be amazing.

----

Well, my RAM is again on stock. And I discovered a strange thing for me, apparently my perfect GTLVREF Lane voltage is 5,5,10,5 with a VTT of 1,40 o_O

I'm not totally stable yet (but close to) so I'll be trying messing with chipset voltages. Yes, I'm trying at 3,60Ghz.

And hey... NF200 Voltage has something to do here?

Edit: (Lol, the "badword" blocker blocks anything, xD)

I'm on 3,60GHz, I've been on, idle for more than 10 hours, and I've been playing lately more than 5 hours, zero problems at all. WinRAR compressing, CPU at 100%, physics stress... and nothing is wrong. I'm sure that passing prime will kick me out but...

...Is really necesary Prime to test stability...? I'm not going to overclock to find huge prime numbers faster. I'm going to overclock for games and multitask, and for eliminate the bottleneck on the SLI. And seems to be perfect...

I was stable at 3.4Ghz with 1.42v in Windows (1.45625v in BIOS), I tried for 3.6Ghz but two cores kept failing Prime95, so I though, screw it! Reset it back to my saved 3.4Ghz profile and it wouldn't POST, it hung on the POST code '02' and sometimes '03' in which it would loop between restarting and those codes, until resetting to stock. With which it'll BOOT.

So I turned it off for a little while, tried again, same thing.
Then I cleared the CMOS with the little red button, tried again, same thing.

I really don't know what's up! Any ideas? Thanks

Ouch, have you tried setting your bios manualy for the OC, or just loading the saved profile? I don't know what else you could try ;l

Yeah, I tried that. I've got it up to 3.2 at the moment, I've just been raising it slowly, instead of making the big jump up from stock.

I'm going to try 3.4 now.

Good luck

I had a scare myself the other day, fell asleep and left my rig folding, I woke up about 4am and shut it down, then went back to sleep, when I got up in the morning I went to turn it on and it wouldn't even post! Fans spinning etc but wouldn't boot D; So I started unplugged stuff and seeing if it would boot, tried one stick of ram, nothing, tried my old ram in and it booted. So I figured my Doms were DEAD. A few hours later I put the doms back in to make sure and they worked. WTH? I was ready to RMA them ;l

[Kornowski]

That's strange, man! So it's working now?

Well, it works at 3.2Ghz, but not at 3.4Ghz, it just goes between '02' and '03' POST codes. I don't get it, it worked perfectly for months before hand with the same settings. I've re-set the CMOS and everything.

Here's my settings;

CPU Core: 1.45625v
CPU FSB: 1.40v
Memory: 2.2v
nForce SPP: 1.50v
NF200: Auto

CPU Ratio: X8
FSB: 1700

That's all for when I had 3.4Ghz.

[GeforceGTS]

Yep it's been working fine since, had me really confused.

That's really strange, have you tried giving it more vcore or using a different multi? if you had tweaked the GTLREF's for 3.4ghz when you save a profile it doesn't save the GTLREF's, I don't think you've touched those though? ;l

[Kornowski]

Nope, I've not tried more vCore, wouldn't have thought it'd need it, since it was working fine. But I'll give it a go, Thanks.

Nope, the GTLREF's are all at default, they've always been.

You ever with you could rewind time!

[GeforceGTS]

Yeah I wouldn't think you'd randomly need more vcore, just grasping at straws Always good to rule out all options though.

[Kornowski]

I'll give it a try, thanks. It's really buggin' me. I wouldn't have thought I'd broken anything, right?
