PC5300 for overclocking

Lo dudes.

I have 4 gig of ram, PC5300 and PC5400.

If I were to get a mobo that overclocked (my current one is vanilla) could I drop down the divider and bring it the ram back up again, as per all Duo/Quad principles? ie would something like an iP35 mobo bring down the ram with a divider (worded as such or otherwise)? reason I ask is that PC5300 and 5400 is prolly the lowest people buy now...but it's good ram, and I don't wanna change it when I'm already happy with the bandwidthm, just fancy a tad more clocks :)

I don't have one here to see the BIOS so I can't tell. Any help, thankfully taken :)

I had a e2180 which has multipler of 10.
I tryed 10*333 = 3.33Ghz Cpu speed. System wouldn't boot.

So what i did was lower the multiplier to 9*333 = 3ghz

Had a 1:1 ratio with the ram 666

And still had the higher FSB which is important.

The bios also does support ram ratios

What CPU is it?

Intel dividers only let you go higher with the RAM.

Generally, you will have straps something like;

CPU/RAM

200/400
200/800
200/1066

266/533 (will often show as 266/667 on P35/X38)
266/800
266/1066

333/667
333/800
333/1066

400/800
400/1066

So, in other words, your minimum RAM speed will always be twice the FSB speed.

An example would be;

You use the 333/667 strap and then set the FSB to 350, you will have 350/750.

Or

If you use the 333/800 strap and set 350FSB, you will have 840Mhz for the RAM.

So, you can't go downwards on Intel boards, just upwards.

Clunk. I'm thick

Can I use PC5300 / 5400 to overclock my cpu on an iP35?

Yes/ No?

Cheers chap

You can run upto 333fsb on an IP35 using the 1:1 CPU:RAM ratio with 5300/5400 at the stock RAM speed.
If it overclocks (like Ballistix 5300 does brilliantly) then you can go further.

Depends on your CPU and what Multi it has 7x/8x/9x etc.

If it's for the quad, which has a 9x multi - then you can get a theoretical overclock of around 3000Mhz before you start to overclock your RAM. (Your RAM is 667Mhz, so going off what I said in the last post, that would make your FSB 333. So, 333x9=3000Mhz ish).

After that, your RAM will be the deciding factor, but lots of people have had good quality lower speed RAM that's gone really high with a notch or two of extra voltage and maybe looser timings.

ok...thats what |I needed to know. Thanks chap :)

I have overclocked my PC 5300 RAM sticks, reaching 856 on their clock and 428 FSB, I have even gone up to 457 FSB, giving 914Mhz for my 667 Mhz!...so yes it is possible...I have kingston sticks though.
