System no longer stable - Big Favour - Testing some X58 kit

Hi,

System Specs:-

Intel i7 920 D0
Gigabyte X58 UD5
12GB Patriot Viper 1600MHz C8
2x Gigabyte GTX 260 OC
5x Hard drives
1x Bluray drive
18W DDC WC pump
Corsair HX620

My system used to be stable running the above at:-

4.2Ghz - 12GB 1200MHz 7-7-7-20-2T - etc

I flashed the BIOS from to 7 (what the board shipped with) to the latest 12. However after I did this the system can barely maintain a stable OC of 3.1GHz :( I have tried flashing back to the same BIOS that I had before, also tried a skeleton system and swapped over all sticks of the ram etc trying to find out what the hell happened, but no luck.

Short of having to buy a CPU/RAM/MOBO this is the only option I have! Just wondering whether anyone here would mind testing a kit of ram and my CPU (so that way I know I have two good components) to see if they are knackered to help me narrow down what may be broken in my rig.

That seems incredibly drastic to me. Surely you forgot to change a voltage in the new bios to match that of the old bios, or the new bios needs you to manually adjust memory voltage/timings.

We CAN solve this for you on here, the chances of a component being faulty given the change was a bios update are very small.

I use Asus boards so I am no help to you really but there are plenty on here with your exact setup...........step in blue PCB boys.
 
You should be able to unequivocally test the RAM by running memtest - unless it produces errors/crashes in which case OK, you don't know if it's the RAM/mobo/CPU. It does seem much more like a BIOS setting though. At the least it'll be a mobo problem resulting from the changed BIOS or the process used to do so, I know little about that, but seems very unlikely to be RAM/CPU-related.

Hope Biffa can help you out.
 
Sure mate, email in trust.
Take it you tried setting the ram manually?

I have tried messing about with everything in the bloody BIOS :( Will email you shortly :)

I know if seems unlikely but I'm genuinely stumped as to what the hell has happened. The system runs rock solid at stock with the ram @ 1200MHz, and with the system at 3.1Ghz. I have never been able to get 12GB to run at the XMP profile though, so it's always been 1200MHz.

However as soon as it's overclocked over this it just starts BSODs all over the place. I haven't run memtest as if it's rock solid stock and slightly overclocked - then it should work with a heavier overclock. I have tried the settings used before the flash on both the newer BIOS and again after I have flashed back - still a no go.

I will give memtest a go, but as above if it works at stock it should work overclocked.

Possible the bios update corrupted your operating system?

Not sure, guess this could be a possibility. I was investigating this and thought I would reinstall Windows 7. But I can't even do that, it just BSODs as soon as it's copied the files across during the installation.

Happy do you have msn anymore?

I don't use it anymore, though that email is still my main email and the one the trust system uses.



Worth mentioning that my temps are fine, just below 70C on all cores using the below settings. I have also removed one of the GTXs incase the PSU was fading etc, but as expected it no difference. These are the most recent set of settings which I have tried, some of the voltages are high, that's just to rule them out:-

I'm sorry, I'm just not seeing the logic behind "if it's solid at a slight overclock, it should work at a higher overclock", "if it works at stock it should work overclocked" or running RAM below rated voltage because it's not being maxed out.
The first two just seem odd (and incorrect) assumptions; the latter silly when trying to figure the cause of the crashes?
 
The IMC on my 920 can't handle 12GB at 1600MHz 8-8-8-24-2T, as such I have always run the system at 1200MHz 7-7-7-20-2T. Because the ram is running well below spec what's the point in pumping extra volts through it?? It's same as people on here who run the CPUs at stock speeds, but undervolt them. For a good 6/7 months the system was rock solid at those settings with the CPU folding most of that time. I was making that 'assumption' about the system, as if it can manage a small overclock it should be able to manage the same clock it was at before - which is true - unless something has degraded/broken (the point of this thread). However everyone was stating that this wasn't the case and that I had missed/overlooked a setting etc.

Just a thought but did you set the bios to defaults after the flash and then re set your oc settings? Also it may seem a coincidental long shot, but maybe your hard drive has just developed a problem as I noticed you said it bluescreened during a fresh install - worth checking perhaps. Also maybe the power supply has suddenly developed a problem as power supplies can cause all sorts of problems and perhaps should not be ruled out until illiminated.

I'm using the hard drive in another system at the moment and that's all fine. But I don't have a 'proper' spare PSU to test against mine. But I'm just going to rule stuff out one by one currently.

One by one is the only way to go. Good luck and let us know how you go.

Well fair enough, but I'd still revert to the rated voltage just while this is going on, to be on the safe side. For example, you'll get laughed out of the shop if you try to take back the RAM complaining that it won't run stable below stock volts :p
 
Sorry if this has been mentioned [it's late!] but have you tried with varying amounts of RAM?

Does it still bum out with just a couple of modules? 12GB is what, 6 modules? That's a lot of RAM that could go wrong.

Only brought this up cos I just had to RMA some RAM! :p

I have run the ram at the proper volts, but I then started lowering volts and it still worked at 1200MHz. However no no matter what settings I use I can't get it stable anything close to the old settings :(

I have broken down the ram to 3x2 kits when testing and was still getting problems. I will test individual sticks depending of what Biffa finds since he can find out what's busted. Since he has a 3 working components to sub in :)
