figure this one out

spec and oc as per sig

Just reinstalled heatsink on cpu , removed gpus/ram/mobo

reseated cpu cooler replaced mobo ram gpu's

booted ok checked temps all ok , ran prime 95 blend test , system locks up

reboot system locks up at loading screen

reboot system locks up after 5 minutes

as its a complete lock up i assume ram , reseat ram check bios settings reboot ........... system locks up

ram is running UNLINKED set manaully to 1066 5/5/5/15 2T

i set the ram to 800mhz same timings and all is well

so after running my ram at 1066 for god knows how long its now decided it wont anymore and im at a complete loss , nothing has changed , i know my bios settings inside out so im 100% certain all is as it has always been in there

If anyone can tell me what the hell has gone wrong i will clean your car and cut your grass for the next six months

Disclaimer...................i wont clean your car or cut your grass

Hi Darren,

Have you tried resetting your BIOS to its defaults and then re-inputting any custom modifications? What does CPUz say about your memory timings as determined by the SPD chip?

Silly question, did you replace the thermal compound?

How old is PSU? very new? can you test to make sure the voltages are good? it might failing and running out of steam. < electric steam

cpuz reports the timings correctly (ocz platinum edition sli ready) as 5/5/5/15 , however if i set the bios timing select to auto it detects 5/7/7/24 which is incorrect , i have tried these timings though but same effect , as with other even slacker timings still no 1066 , i can run at 4/4/4/10 at 800mhz though which i am considering as an alternative

voltage set at 2.2v which is the upper limit

oh and yes tried a bios reset still no dice even with everything at stock

yes it is a silly question no seriously thoiugh mate i cleaned the cpu and hs with an alcahol based cleaner and reapplied AS5 , my temps are already a good 3-4 degrees down

voltages are rock solid , even the vdroop on the cpu is minimal

thanks for the help.....keep it coming

Can you post some CPU-Z screenies so we know what all we are looking at?

Also you probably know. all sticks will run at the speed of the lowest stick. Try maybe testing one at a time to see if each can be changed individually.

Edit: Also, if the sticks are sets, then they might be set to run in specific channels. did you place them back in exactly the same channels you took them out of?

there are 4 sticks 1gb each all sticks same size same speed same manufacturing code , 2x 1gb sticks matched pair , 2 sets of these , 4 sticks in all running dual channel , it doesnt matter which slots as they are all the same , but i have put each matched pair into corresponding channels just incase

this ram

it is 1066 , my mobo supports 1066 and my cpu supports 1066 , and its been running at 1066 for the best part of a year now

If I'm reading this right, the only thing you actually did was reapply thermal compound; and to do that, you removed the RAM, the gpu and the motherboard from the case, right?

I would check to see if your board's wiring is properly attached; I would blow out (gently, with air) my dimm slots as particles may have gotten in them; and I would make sure my board was securely fastened to the case.

yep thats all i did , its a new case recently built a all cables managed and routed around the back of the case and all securely fixed ive had issues with pcs ive repaired in th past having bad or no connections to points on the ram sticks , in that case they fail completely , this ram works fine at 950mhz at 800mhz i can run the timings at 4/4/4/10 so i dont think there is anything wrong with any of my connections/hardware.

Its getting to be an obsession now at 800mhz and 4/4/4/10 read writes and latency are on par with 5/5/5/15 1066mhz , it will run fine at the slower mhz/tighter timings..................but thats not the point anymore , i need to find out what the hells gone on for my own sanity

If the BIOS timing is set to AUTO, what does CPU-Z give you, I think we need some screen shots, you could be making this all up.

You upgrade the BIOS of that XFX 780i to the latest?

My old PC, my wife's current () has to have manual settings or the dummy mobo under clocks it, I feel your pain.
