Ok, im having some random freezing for no reason, feels like sometimes i can do anything for hours and no problems, sometimes it freezes, i have passed prime blend and memtest for hours with the current setup.....anyone else, im in line for a step up, i think im going for the 790i, if not im gettind rid of this board......anyone else get this??? plus the fsb holes are hindering my cpu, its capable of 3.85ghz perfectly stable, but thisboard has some nasty holes.

I'm very impressed GutterZ!

I'm assuming you just did that for one suicide run on 3Dmarks? That is an incredible score though. I'm sitting at 18k... a little more actually but not much.

How did you get your GPU clocks so high? I'm assuming you did a volt mod?

I was wondering... I'm running 2x2GB kit of OCZ reaper. I made the mistake of getting the pc6400 kit. Right now my settings are unlinked 1800mhz FSB and 800mhz memory. It's 9:8 in cpu-z. Timings 4-4-4-15-2T.

I was thinking that I might try to go for linked and 1:1 or sync for 900mhz. I'll have to loosen up a bit 5-5-5-15.

Should this perform better? Should I try 1T timings? Would 1T perform better?

Also I cant boot past 4300mhz. What's the deal with that? I cant help think that it's Windows Vista but people here have vista and are booting at 4500mhz.

ok backed memory down to 800mhz, i think this is the cause for the random freezing, this board has problems running memory at higher frequency at high fsb, 1600+

This is too true.

I have RMA'd 3 680i's and 1 780 over the last 14 months or so.

I was only trying to run 1600 FSB with divider to hit 1066mHz memory.

I never cranked any voltages up to crazy levels for the oc's , 2.1 -2.2v on the ram depending which kit i was using and normal mobo volts for a conservative 1600 mHz OC.

The boards would all invariably end up unstable after a few months and require lower and lower mem speeds to remain stable, untill they'd just start throwing me C1 errors at boot-up and locking up while running.

I learned my lesson and just started using 800mHz on the memory since those days.

No volt mod just upped the MCP voltage. I realy have put no time into overclockin the cards, Hwbot gives me a poor rating for my cards :( The case temp was 25f there on stock coolers. Ive never tried 1T just link an sink.
I put on optimal settings boot it then go an see were there at an lower them. If it flys then cool if not I keep turning dials 1 at a time.
I realy cant help ya to well. I just went intel 5 months ago an had only brief experiance with the AMD 4600. So Im still learning to. Its just a process of elimination going for stability or that high. Besides once you get your highest bench or most stabilist max FSb or Cpu speed, the fun is over! Now you got to buy something else.

GutterZ... what was your voltage set to when you did 4900mhz?

I maxed out vcore which i think is 1.8v an 1.78 after vdrop...
Everest shows it in the lower right... Thats my best Super PI 1M too
not to bad for a dual core.

I have 2 an both go that high with the E8400. My only beef is Vcore stops at 1.8v. 1.78 after vdrop
An thats what I had for them scores. It booted 5.0ghz but no windows action
I wanted to go higher but was out of vcore. I feel if ya want to Bar-B-Q a chip i should be able too. I doubt evga will release a bios with any higher vcore.

I still run the chip at 4050 for 24/7 with the same vcore I had before them overkill voltage runs. maybe once i get my chiller up an running the results will be differant. 780i FTW

Also got a E8400, cuold you post your bios settings?
I would like to have it 4.0 Stable? Thinks it will manage??

Yeah man, i have done a step up with eVGA, and will have my new 790i soon.

Here are my settings for 4050 on the 780i
Multiplier 9X
FSB 1800
Cpu core is 1.41250, Real is 1.38 such as CPU-Z reading an bios
Fsb is 1.3v
memory is 2.1v
SPP 1.50 this is the main factor of my stability
GTLVREF auto of 00mv

Hope this helps.
My Vid 1.1125 on my chip

Sweet dual core scores man.

You've almost caught up to my quad/G92 SLI scores!

How much was it?

1.632v on air.. thats madness. Not even worth the risk of totally burning that chip to pieces

To each their own.

If he knows the risks and wants to crank the juice anyhow, then more power to him!

how much voltage is too much voltage?

That's a question that can start a whole other 50 page thread...

Oh wait it has :)

For me anything over 1.6v without super heavy cooling like dry ice cooling or super powerful watercooling.

I probably should have started something lower to start with. The truth is I rushed the overclock to 4500mhz and wanted to pass 3dmark to see what I get! I got greedy! I saw I guy do 1.8v @ 4900 here and wanted to give it a shot.

So what the heck! I tried it. The weird thing is I had to have the memory unlinked to 800mhz. When I had it linked it wouldnt boot. I had it set to 5:4 though. I wonder why it wouldnt boot. It's the same essentially right? I thought it would be the other way around.

Im thinking about getting the 790i.. just need to figure out how much the step-up is before i do it.. GAR how much was it :up:

Its more stress on the mobo to do linked.. I think thats the problem.. I cant get linked : auto on this board at 1780QDR.. Its just flaky like that, im not sure whats making it do it either

Not happy to hear that, just got this board set up today. I had the same deal with my 650i. Looks like 3.6/1066 will be my everyday, and 4.0/800 for bench. Mine has the P02 bios, should I stick with that?

Is the nvidia 780i chipset known for having poor SATA performance? (Reason i ask is that i just ran some HDD benchies on my system and the results were alot lower then i expected)

sorry i cant help ya Dragon.
just wanted to share my preliminary results with a xeon 3070 so far.7x525 3.7 1.475v mem 1:1(1050)2.2v,spp 1.45,mcp 1.5v.been running orthos blend for a half hour so far.im very impressed with this mb.cant wait to test a q6600 on it.

Hi guys , I have not read this whole thread yet but I will . I have an x3350 on the way , is it worth trying it on my evga 780i ? How has the max fsb turned out on these with quad core ?

Well I was stuck at 1800 FSB with a E8400.
But after a month at that speed, I change some voltages, I am currently running 100% at 1900 FSB (475*9=4275) on air cooling.
Wow this board is not that bad at all.
790i and ddr3 plus 1000w PS is not in my budget, LOL.
