Re: GB x48-DQ6 and my nightmares...

Have you ever tried running only 2 RAM sticks? 4 can often cause instability especially when you don't have good airflow in your case and they aren't cooled properly.
In order to isolate the problem it would also be a good idea to jsut connect the hardware that's absolutely needed, you've got a lot of stuff there and it could be a lot of things causing the problems.

The first thing you should try is run Prime 95 in blend mode and see if you get any errors there, since you're not overclocking any problems found by Prime will likely be caused by your RAM.

Re: GB x48-DQ6 and my nightmares...

Thanks for the quick reply m8...I've tried every combination of memory slots/sticks and always end up having a crash. Currently the problem is pretty sporadic but it's annoying none the less. I can sometimes go a week without issue and then one night the ball drops and 3-4 crashes...either BSoD or Video driver recovery.

I've also tested the components in different machines without problems. The memory was the first thing I tested and replaced (strangely the first batch of 996599 I had only crashed during the windows memory diag but never in memtest...). The current batch of 996599 is now 1.5 months old....actually I don't think there is a component in the machine which is more than 2 months old now and yes I know age makes no difference as it can still run and be "bad".

As for air flow...this Lian-Li has some awesome airflow, just have a look @ some google images... ;-) Best case I've had and well worth the money spent believe me!

Edit:
also bear in mind the 2 WD Blacks are not used atm...so there really isn't THAT much in there...and I'm 99% sure the Enermax is not the problem :)

You need actual airflow on top of the RAMs sometimes, I can't run my 4x2GB OCZ on an open test bench at 21C room temperature unless I put a Corsair Airflow Fan on top of them. Airflow from front to back in the case won't help much there.

You should try if Prime 95 gives you errors in blend mode, if yes then the problem is very RAM or board related and we can look into those then.

Re: GB x48-DQ6 and my nightmares...

Yeah I did as you asked about 15 minutes ago actually and there was an error in prime. Now I'm running sisoft burnin to see if anything shows up there too...I'm noticing (during sisoft tests) too that the cpu temp is around 52c...should I be concerned about that?

Re: GB x48-DQ6 and my nightmares...

Try only 2 RAM sticsk in Prime then, if you get terrors in prime, RAM is the most likely candiate here with your CPU at stock speed.

Re: GB x48-DQ6 and my nightmares...

Man I tell you what...I always loved Mushkin but if this is the SECOND set of 8GB memory that I have to replace it will be the last :S

Would a DRAM:FSB Ratio of 16:10 be normal for this if the memory is using the EPP profile?

**Nickel020** · 03-10-2009, 01:05 PM

Re: GB x48-DQ6 and my nightmares...

Yes, 16:10 is the same as 3.20 (160 divided by then x 2, the effective frequency is used Gigabyte, not real frequency) and 333 x 3.2 = 1066

You should also try the RAM at DDR 800 and see how that works (system memory multiplier set to 2.40B).

Re: GB x48-DQ6 and my nightmares...

I'll do that after this test of prime with 2 sticks...running now ;-)

Re: GB x48-DQ6 and my nightmares...

I had a similar prob and it ended up I needed to increase the voltage to the northbridge by a small amount to have perfect stability. 100% on multiple passes in memtest, prime95 & intel burn test. This is on a non overclocked pc with same board and chip. Memory was Corsair Dominator & Kingston HyperX

**MoridinEU** · 03-10-2009, 04:03 PM

Re: GB x48-DQ6 and my nightmares...

Thx for the tip...I usually try to stay away from upping voltages unless absolutely necessary. It'd be a real shame if I can't use al 8GB of this memory... :(

**sb_** · 03-10-2009, 05:08 PM

Re: GB x48-DQ6 and my nightmares...

I'm the same in regards to the voltages. Thing was I tested everything on my x38-ds5 and another board and they ran perfectly with no adjustments.

I'd also have a feel of the NB heatsink and see how hot its getting. If its getting very hot, take the side of the case off and if possible position a fan over that area and run some tests. If nothing fails then there is your problem. I've got a 80mm fan directed on to the NB heatsink. I positioned it by stacking 7 motherboard standoff on top of eachother and then screwing them in to hole next to the NB heatsink when there currently is just a normal screw. Quick and easy solution

Re: GB x48-DQ6 and my nightmares...

Ya, MCH/NB Voltage is likely needed for sure for 8GB. And you may be well off with some SB Voltage adjustments as well for all your drives. Increasing NB voltage is a normal and most often needed thing with 4-8GB or more, any ram/board will need this so it is not just that type so you know.

If you will tell me your model # I can give you some full suggested settings.

Post for me what you are using now, and your model # and I will advise back >>

Re: GB x48-DQ6 and my nightmares...

Thanks, as soon as I get home I'll post this info for you. I actually adjusted the NB voltage to +0.05 and prime lasted until test 9 but still threw an error. In prime...when running blend benchmark are the workers actually cpu cores or mem slots? I ask cause it's always the same 2 workers which throw errors...
