Phenom II x2 555 unlock - Page 3

post #21 of 58
It's not a problem per se, but it will severely limit actual performance, as the memory will be running at half speed or less in that setup. You need memory in pairs for best performance on anything except a socket 1366 Intel machine. Pull one stick out, and make sure the other 2 are in the same bank (usually signified by slot colour) and see if that helps. If it does, look out for a single matching stick, or buy another triple set, take one out and sell off the remaining pair

Edit: OP: Go hit the +rep button below particularly helpful posts to properly thank people who helped out. Not me, since I mentioned it, but go thank all the others who've helped so far. Spread the love!

well spotted zamdam
3 sticks will run in tripple channel
and two will run in dual?

is there anything i'll have to change in BIOS or just pull one out?
is this a likely cause of my unlock fault, and why does it only occur in games, and only when my cores unlocked

Just pull one out or get another one to run 4 sticks.. You do not have to change anything in the bios
..

EDIT.. also, intel x58 is the only chipset that runs triple channel memory..

Will do, untill my next stick comes in. Thank you all for that info on the ram, I'm still new to computer building. But this is irrelevent to the graphics/unlocking issue or am I mistaken?

Let me explain:
For most systems, they only have a dual channel memory controller, which means since 3 sticks is not in pairs, they run in single channel mode. Only the Intel i7 has a triple channel memory controller currently, so anything else will run the memory at half speed or less if it's not in a configuration that matches a dual channel mode.
With the memory in single channel mode, it's running WAY below it's correct speed, which will cause severe memory lag in games.
Now this may not fix the problem, but you do need to run only 2 or 4 sticks in your system for maximum memory performance, anything else will cause slowdowns and problems. I had the same trouble with the machine on my big-screen, it had display glitches all the time, then I swapped around the memory so it was in matched pairs in the right slots, and it was massively improved.

Fixing the memory setup so it gives best speed is the easiest of the possible fixes, you just need to pull one out.
BIOS updates on modern machines don't need a floppy disk any more, they can usually do it from a simple USB stick. Check the board manual for how to do it, then go look up your board on Asus.com and look for updated BIOS files.

Thats what we are here for.. Some help and some tell you to go read read read.. i hate that.. but anyways..

It probably isnt causing the flickering issues you are having.

If you look at my other rig in my profile, its a HTPC with a 555BE.

I have unlocked the other two cores making it a B55 quad core and it runs fine with everything i do.

BUT.. if i leave it on all night and come back the next day, the screen will have some horizontal lines flickering across the screen when i move the mouse or click on anything, or even when i try to play a movie.. I dont know if it has to do with my cpu not having four stable cores or if its my video card getting warm..

I have since set it back to a dual core but it seems to still happen but not after the first day.. it takes about 3 days of non stop running for it to give those same awesome lines across the screen.

Very helpful, Understand much better now. Scary that I've been running single channel

You should actually say, the Intel X58 chipset supports triple channel memory.. or socket 1366

For instance

i7-870 only supports dual channel memory.. Because its H55/P55 Chipset and not a X58
