Prime blend error

I just tried running blend to test my system and it failed straight away with the error "No FFT lengths found in the range specified. What am I doing wrong here, I never had to set any values manually before?!
 
Go to the folder where Prime is located and delete the prime.txt and local.txt files, this will reset Prime to default values, it might help.

Tried that but it didn't work. I think I might've had a dodgy version as I've just downloaded it from a different site and it works fine now. What version is everyone using? This new one is 26.6.
 
Thanks, seems like I'm on the right one now then!

Ok so blend fails on 2 cores after only 8 minutes, my initial thought was that the vcore (1.2375v) is too low but I managed 10 passes on IBT at max settings so this makes me think otherwise. I am using 4 sticks of RAM for the first time so maybe the NB needs more juice, it's at 1.3v atm.
 
Been fiddling with the BIOS all day & I still can't get the bloody thing stable :(

This board doesn't seem to like me using 4 DIMMs as I can run blend fine when I try 2 sticks at a time. The most stable I've managed with all 4 sticks is 38 mins of blend before 1 core fails. The thing that makes no sense though is that that was with 1.38v going through the NB but after upping it to 1.4v it fails after only 8 mins??

Anyone got any tips to make this mobo (or any P45 board!) play nice with 8GB of RAM and an overclocked quad? It's 4 sticks of OCZ Platinum 8500 that I'm using.
 
The first set of tests that Prime runs when you are running it set on Blend is Large FFT's, it then runs Small FFT's, then large again and carries on like that until you stop it.
Large FFT's stress the nuts out of your memory, so if you are failing after 8 mins, your problem is more likely to be memory related.
 
That's what I thought & hence upping the NB volts as I've doubled the amount of RAM in my system.

As voltage wasn't getting me anywhere, I decided to play with the memory dividers & I managed a 3 hour run earlier @ 960MHz. It'll be a shame if the board can't run 4 sticks at the frequency it says it can but the increased CPU speed makes up for it I guess!
