how do i go faster?

[omegaman]

Hi

got a 4800 x2 running at 2.8, how do i get it to go faster,also 2 x xfx 7800 gtx's will not no past standard clock speed(450).

custom pc - 1.56

3d mark 2003 - 29780

3d mark 2005 - 13550

aquamark - 111 000

any ideas will be appreciated

Thanks

That's a nice system

What temps are you getting?

Unless you are on Mach2 GT or r507 you might no go much higher on the CPU, also my CPU has the heatspreader removed to get better contact on both cores..

Check out this thread to go faster on your GFX cards:

if its better 3d marks ur after swap ur x2 for my fx 57......

same here m8, just wondering how the hell you guys get the X2 4800+ to run at speeds of 3000MHz or higher. Has anyone got it running themselves. I have a Mach 2 GT(r507) and the highest i get to run benchies stable is roughly 2980MHz (248 * 12) over the default 2400MHz. Also my 3D mark 05 scores are only 13200 or there about using 2 BFG 7800GTX cards in SLI?? Just using the standard heatsink and fan for the GPU at present while OC'ing it.

CPU core at 1.44 memory at 2.90. Using DFI-SLI DR mobo and memory is OCZ 4200. GSkill 4400 died...

Using NVidia's 78.80 or something like that?? drivers at maximum performance settings...core 480 and memory 1330

Anybody have any ideas of how i could get better 3D mark 05 results (other than getting an FX chip or water cooling the GPU setup or volt modding the GPU cards) Also how else can i get the cpu clocked higher? Would setting the FSB up to 300 and multiplier at 10 help??......instead of the current 248 and 12. Of course i would have to get memory that can run at DDR 600 stable...what choices of memory is best for this mobo?

I know i have asked many questions in this one post BUT any help given will be greatly appreciated.

Thanks in advance.

BH-5 will rock in the DFI coz of the voltage options. Good TCCD is also worth looking at.

i`ve never used an X2, so cant say if the voltage increases work differently, but your CPU voltage is pretty low for a high clock speed...your 2980 on 1.44V is pretty damn good.

sorry, cant think of anything else...i`m tired

Okay firstly the benchmark results you see in 3d for me is with an FX55 @ 3.511Ghz with two volt modded 7800GTX's running at 600/1400.

I will post some x2 scores when I get my 2nd GTX back.

I achieve a 261*12 overclock with my 4800 - it overclocks as good because (I believe) it has had the metal heatspreader removed from the CPU itself and but using a 2mm thick square shim of pure copper (between the mach head and the exposed cores) I get better contact on both cores which equals lower temps and higher overclock. Don't forget to use ceramique not alumina thermal compound as it help shave a degree or two off the temps.

At stock volts I can get 250*12 (3Ghz) but I need 1.6v (1.425x113%) to achieve any better, if I go over 1.6v the unit becomes incredibly hot (by comparison) and unstable. So your overclock of 248*12 is close to what I am able to achieve you just need to play with the vcore a little.

You might want to look at increasing the contact on the CPU by cutting 5mm ofh the end of the bolts or by introducing more washers to each bolt this allows the head to make better contact with the core which in turn will help improve your temperatures under load.

On the DFI always use the special VID control to increase your overclock as for some reason this produces a more stable system thasn just increasing the vcore.

My LDT voltage is set at 1.4v and my chipset is set at 1.6v.

BH5 or VX or Redline is much better ram for the 4800 under phase as the memcontroller is limiting the FSB overclock at sub-zero temps and 270FSB is probably the best you can expect, so opting for between 250 and 260 using BH5/VX or Reldiline RAM on a X2 means you can run at your memory at 2-2-2-5 (they all do 260+ at these timings) which offsets the lower bandwidth allowed by the memory controller at sub zero temps.

For tips and tweaks of how to increase your 3dmark scores go to the 3d section of this forum and look up my tips and tweaks.

I am using the 623-X BIOS which I have found to be awesome

Hope this helps - good luck and may the force be with you.

Always best to post yoru system specification when asking questions like these - look at my sig for the sort of details you should be providing - my tips are based on assumptions - posting your actual specs would be of great use.
