UD3LR 8gb memory crash

Re: UD3LR 8gb memory crash

With highset being the worse, am I understanding correctly?
It's a pitty you haven't done it with 333FSB @ 3GHz, we would have a ground for comparison.
BTW one good reason I can think of for safety margin is fall in power voltage as result of lightening e.g., it will only cause a small drop in VDIMM and MCH Core, but may be enough to cause memory data corruption with lower tRFC.

Re: UD3LR 8gb memory crash

is memory data corruption temporary or what, theres a storm here now lol

also tomorrow im getting a zalman fan could i ask for help with ocing the cpu in the same thread here?

Re: UD3LR 8gb memory crash

Yes, the lower the time the better.

I used stock to make it a fair test. As you have DDR3, my results wouldn't be directly comparable to yours as I'm running DDR2.

There wouldn't be any significant VDIMM drop that would cause instability as the board regulates this extremely well. In the event of a power surge or lightning strike big enough to effect those voltages it's likely that the PC would crash regardless of settings.

RAM data corruption is temporary. It CAN however result in corrupt data being written to the hard drive, which can cause data loss. This is why backing up important files is a must before you start overclocking, followed by a thorough stress test after to verify stability.

Yeah, dosn't mean the RAM is fried, and that's one reason Windows shuts into the BSOD or restarts if it's diabled when detecting possible memory corruption, to prevent such possible corruption on the disk.

Re: UD3LR 8gb memory crash

Ha that was fun i got my zalman 9700nt in place, also one synthe fan, the screws that came with them dont really work lol. So im going to wait to get some foam tape to secure them in.

So i guess im ready to do some overclocking where do i start?

I see the HS retention kit is the same I had with CNPS8700 which I immediatly broke the little L piece that locks it and had to improvise a substitute from a paper clip. I had no problem with the screws though.

Save the settings and make somebaseline benchmark.
I think 400FSB would be just right to begin with.
Before you change it, set all voltages except references manually to their suggested values (those you haven't changed yet) or the target values in EasyTyne that should be the same. Also set PCI Erxpress frequency to 100.
Set 400FSB with low CPU Ratio, even underclocking the CPU to get stable memory settings. Select new memory multiplier. Static tRead increase is probably needed, and maybe more MCH Core, what's it's value now?
Sometimes 400FSB does not work, you can try 401/399 unstead.
When memory is stable you can increase CPU Ratio that would likely need more VCore.
Keep an eye on temps.

Oh and post some settings to refresh our memory.

Re: UD3LR 8gb memory crash

I didnt use the L retention peice i used the one that just lays of the middle of the HS and screws into the black plastic two screws and one metal peice, seems like it would be very hard to break it haha. I think i know what peice your talking about i was worried why i had an extra 2 metal parts haha

I did not have that option. It was an "OEM" package, this probably "fell out the box" LOL or this HS don't have this option.

Re: UD3LR 8gb memory crash

can i splice two fans onto one fan header, only one of the sys_fan headers have speed control so my case gets extremly loud when i plug my other one in.
Yes im taking the OCing very slow sorry

Re: UD3LR 8gb memory crash

Personally I wouldn't recommend connecting more than one fan per header. For any extra fans, the ideal solution is an adapter to connect them to a 4 pin molex PSU connector. You can buy ones with three outputs on the same adapter, a 12V plug a 7V plug (using 12V as positive and 5V as ground, 12V - 5V = 7V) and 5V. You can also buy various in line resistors to use in conjunction with a normal 12V molex adapter. 9V, 7V and 5V are common choices.

Running a fan on 7V can reduce noise dramatically, while still maintaining decent air flow.

Re: UD3LR 8gb memory crash

is there anyway to lower the speed without purchasing anything?

[Psycho101]

Re: UD3LR 8gb memory crash

No. I certainly wouldn't recommend you splice wires tc.

The adapters we're talking about cost a couple of pounds/dollars, they're not expensive. Try somewhere like Radioshack/Maplins or an online specialist.
