Prime95 problems with no overclock

[Hawkest]

I've been trying to better my previous overclock of 3.6 on my system never ran prime before always just used a Aida...

So I decided to see how stable my system was so I ran the blend test which runs for a couple of hours then hangs my system (needs a hard reset everything freezes and screen goes blank), I tried the large and that did the same except screen stayed on, I ran the small and prime95 crashed system worked fine after closing prime.

And this happens at default settings as well.

Antes carbide 540 air
Q9550 E0, idle temp is about 33℃ Max 58℃
Striker 2 extreme with most recent bios, corsair value memory @ 1333 9-9-9-24 t1 (best mention here that I've ran memtest on the ram for 4 hours and had 0 errors),
Gtx 570,
Antes quattro 850w

I'm a little stuck as to what to do... I'd like to make sure I have a stable system before I try and squeeze extra performance out if it.. other than the ram I know my system should be capable of hitting at least 3.8GHz

Cheers for any help..

IMO it's the nForce 790I chipset that Nvidia never patched. DDR3 on socket 775 boards is a crapshoot at best. Read the reviews on that board about all the crashing & freezing.. Many people just gave up and got a different board.
Have you cranked up voltage any?

Cheers burpo,

Yup, I've increased voltages a little here and there, but I would have assumed that default should be stable regardless.. do I need to up the NB voltage a little and repeat testing?...

I noted down all the voltages the motherboard sets at default with a min and Max... will post when I get my notes

I think it's the nForce 790i with PCI-e 2.0 and ddr3 1600 support.
Intel never offered anything above DDR3 1066.. It may fail serious stress tests above that speed..
Good luck..

I had (have) the Striker Extreme 680i, and had some trouble with it. It's now in a WHS server box, and I'm planning to either replace it altogether with an IB/z68 system and 2012 Essentials, or replace the motherboard with an EVGA 780i board before I decommission it entirely, but the IB/z68/Win2012 project goes forward with resolve.

I could say that even a Yorkfield with LGA-775 is getting a bit old, but the NVidia chipset just makes it a bit worse. If you can use it for something as I did, that's great. But I had all sorts of struggles with drivers and the nForce storage controller wasn't AHCI-compliant. I finally just turned off the controller and put two identical PCI-E SATA-III controllers into the system. But even that is slowed down by the PCI-E 1.0 bandwidth potential.

So? The WHS server was a success, but I went to a lot of trouble making it "perfect." There's just a point in time when you have to cut bait and give up certain parts of old technology that was the center of disputes between Intel and NVidia, couldn't make the same motherboard (680i) more than Wolfdale-capable, and truth be told -- even I had troubles with using all four slots for RAM. It seems to work find with 4x 2GB G.SKILL DDR2-800 "PQ" RAM. I think I had to update the BIOS before it would. And I'd had problems with that, too -- a reason I ordered a pre-programmed PLCC BIOS chip with the right BIOS version.

So if I under clock the ram to 1066 then see what happens... might try that and see if helps if not could that mean it's a god chance that it's something else?

And again . . . if the 790i represents a transition in RAM from DDR2 (780i) to DDR3, the other remarks here coincide with it in pointing out likely limitations.

You can find things for which to use the old Yorkfield system, as I said. But your overclocking sweat and tears are better spent on something that is at least post-Nehalem in a chipset that lasted for a while.

Your pretty much wiping a dead horse these days for anything other than general usage I guess.

The wife still uses a Q9650 old gaming build of mine mainly for web surfing and a few things these days, she uses her tablet most of the time when at home.

I even have a set of these in it, they were odd ball ram att. New egg sold them for less than a day I think, they sold out and they were never restocked.

And you were limited to one set.

Just a blast from the past, they still work fine

Sorry posted before I'd read your comment bonzaiduck.... will read in a bit...
