amd x6 1090t OC question

post #1 of 7
Thread Starter 
So this is the trouble i'm running into. I'm some what new to oc ing. I oc'd my 965BE up to 3952mhz. i'm trying to overclock this x6 but am running into trouble. I bumped up the multiplier so i was at 3.6 and ran prime to see if it was stable. i got a error after a few minutes . It was on my sixth core it reported error and stopped stressing but the other 5 cores kept going. I downed it to 3.5. same thing. 6th core shuts down and the other 5 ran for 7 hours when i was out. Not sure why its doing that? could it be a bad chip ? or does it really need more voltage to go up that little? from what i read 3.6 should be do able on stock voltage. So i'm not sure where to go from here. close to just turning of that core and clocking the 5 of them and see how high i can get. Any thoughts? Oh and its not a BE but i can change the multiplier in the bios? i thought i had to have a BE to do that? does my mobo support multiplier changes in general then?

My system:



cpu : amd x6 1090t
motherboard: asus m4a88t-m
memory: 12gb patriot 1333EL series
video: evga 450 gts oc'd to 900mhz

first your motherboard has a 4+1 power phase, so you should be careful with your OC. you won't get high OC because of your motherboard.
second can you please give use your Vcore voltage ? and what is your CPU/NB frequency and voltage? and what is your HT frequency?

you need to increase your vcore (CPU voltage). try 1.35V @ 3.6GHz. The difference between 1090T BE and normal 1090T is that with the BE you can set your multiplier up to x40 I think, however in the normal 1090T you are locked to 16x multiplier. and yes all motherboard support multiplier change, even yours.

It's a RAM problem
You really should run only 8 GB.in the proper slots .so you're doing dual channel.You're gimping your system with that extra stick.
Set your RAM timings manually to manufacturer specs..and make sure your dram voltage is right

Ok. Just to make sure. Running 3 x 4gb = 12 makes it run slower? How much slower or just when trying to Oc it ?

The difference is fairly significant -- more than what the extra stick of ram will give in return.

If you want to test it yourself; download maxxmem.

Run in both configurations. Make sure the 3rd stick removed is the correct one, and the 2 remaining are setup in dual channel -- this will show you.

As for the processor, I'd be very, very careful when pushing it, since the phase control is only 4+1.

Most people will see no use for over 8GB.  I don't and I often run RAM-intensive tasks such as HD 1080p video editing.

Windows optimizes regardless of RAM channel setup.  That means your RAM usage can go over 8GB unnecessarily and with no performance benefit by doing so - instead a performance loss as the setup reverts to single channel (it can run in dual channel up to 8GB addressed but not when 12GB are - flex memory standard).  Again, most people will see no use for over 8GB.

PLUS, having 3 DIMMs over 2 puts additional stress on the IMC, making CPU-NB stability maintenance tougher.

 

The motherboard VRM system should be cooled before any overclocking attempt but it can handle an OC fine with the proper cooling due to quality parts.  Over-current-protection is also present on this motherboard; you may find this to limit your performance due to overloading/overheating VRMs, causing CPU throttling, if your VRMs are not properly cooled down.  Amp capacity reduces with heat.
