Overclockable Mobo fot LGA775

[alphakp295]

hey everyone,

I'm trying to upgrade my mobo, bad axe 2, to another one with better performance. I know all mobos are capable with OC, but most don't OC well with 4 stix of ram. Mine OCed well with my old e4300 to 3.6ghz, but can't go over 2.5 w/ quad core w/ 4 stix ddr2

Here are my requirements:
- OC quad core w/ 4 stix ddr2 to above 3ghz q6600
- need crossfire capable
- 1 pcie x1 and 1 pci
- price of less than 280 usd incl. tax and s&h..

let me know ur ideas.
thanx in advance.

What's your mobo? It might just need a bios update.

If the BIOS update doesn't work you could get either a P45 or X48 board. Both chipsets are Crossfire capable and support PCIe 2.0. The X48 does 16x by 16x while the P45 does 8x by 8x.

I thought the x48 chipsets did 8x by 8x aswel? Maybe not . . .

Nope, the P45 is 8x 8x.
It is, however, the best overclocking chipset around right now. Any P965, P35, x38/48, or a newer nVidia chipset will get you 3.0Ghz on a Q6600. All it has to do is run at 1333FSB (333Mhz). Most of the before mentioned Mb's will allow you to push 400Mhz which can get you a 3.6Ghz Oc on a Q6600 (depending on the quality of your silicon).

Well,

If say you compare: (on a crossfire system, with the same GPU's maybe 4870's)
16x by 16x
to
8x by 8x

There really shouldnt be much difference rite? As they dont use the full bandwidth?

This assumes same CPU, MEM etc....

DFI does well with four sticks.

This is the one I would pick.

Here is a graph from Toms review of the x48 boards and the ones that did better were the DDR3 boards.

That's what I would think, but this review states otherwise. I still think 8x8 is enough, and I think TweakTown failed to take into account all the other little things that could give the X48 such an advantage. But at 2560x1600 the extra bandwidth afforded by 16x16 helps when textures have to be swapped to main memory. Alas, when textures are swapping to main memory your FPS will suck regardless of how fast the PCIe link is.

So basically I think 8x8 is enough

I looked up DFI's lineup for intel chipsets...
and... there was dark?? version and LT?? version and UT.. which I'm familar with...
Dark version seems very cheap compare to other vendors and dfi's other lineups...
Why is that cheap? is it like... low quality parts??
As long as I can go over 3ghz WITH 4 stix of ddr2, it'll be a minor issue to have x8 or x16 I guess...

It seems like reviews state there's difference for 2560+ resolution...
I'll be using it for my 22", which has 1680 x 1050...
do you guys think 8x8 will have disadvantage compare to 16x16??
I currently use 8x8 pcie setup using two 3870s.
Despite 8x8 or 16x16 then....
must use ddr2 since that's what I have, and I won't want to invest $$$ on ddr3 rams...

So... one of recommendation was for DFI Lanparty LT x48...
Any other possible product??? or no other choice??

 

[Ancient_1]

The dark are cheaper boards that are 4~6 layer (depending on model) and don't use the 8-phase power like the LT and UT. The LT and UT are the same board other than the chipset cooling solution and both are 6-layer 8-phase boards.

One other thing with the layout of the LT/UT boards is with two dual slot vid cards it will have two PCI and ONE PCI-E slots open where the DK boards will only have the two PCI.

Thanks because ive just recieved an Asus P5Q-E today, lovly looking thing! Just waiting on my q6600 now :\

kkthanksbye

Would you be kind enough to post ur result w/ p5q-e w/ oc?
that's if you're going to oc....
and do you have 4 stix of ram??
