Overclock RAM Confusion

[NightshadowUK]

Thanks specofdust, I've done some reading on the forums and it's led to this question:

Will using the BIOS memory divider on Corsair's Value Select lead to me having a at the RAM speed?

[specofdust]

I don't see why it would. Athlon XP systems hated dividers, but AMD A64 and Intel systems dont mind them. I'm not fully sure I understand what you mean though, if you could clarify you're question, that'd be great

If you mean will using a divider effect your RAM speeds, then no, I dont see why it would

[NightshadowUK]

Haha, sorry man. I was led to believe that altering the divider lowered your memory speed so you could achieve a better CPU overclock... I'm not 100% though. The previous question was asking if the lowered RAM speed would make a system noticeably slower?

Using value RAM means having to use a divider. What ole spec is not saying is that this means underclocking your RAM for most speeds (the alternative would be to loweryour CPU OC instead).

Thus the difference between the two systems is not best looked at in terms of what the speed difference is at stock, coz yeah it's only the odd FPS or so, but at what the difference is when you ramp the speed up.

At Scan's today only you can pick up these for £191.47: http://www.scan.co.uk/products/produ...oductID=284445

The value RAM costs £163.08:

I doubt whether £28 anywhere else will get you as much of a performance boost.

Ok, I may be missing something obvious here.

But running your ram at 200FSB is pretty much all you need.

The advantages of having your ram at 240 over 200 are highly questionable for games, and many other things.

This means if you want a high CPU clock speed you'll need to use a divider, but it doesn't mean you need to underclock your ram, or anything like that

Ah, I see you don't understand how the memory divider works.

Some boards are very specific about the dividers, but the ASUS A8N just lets you set a maximum speed.

As you like xstremesytems forums, I suggest you read this thread:

Now hopefully you'll realise that you don't often hit 200 when you use a divider, although you may not be that far away, depending on how many dividers the board has.

Alright, thanks for your help guys, I think I'm gonna go with these sexy little things. From what little I know about RAM Thorsson's recommendation was a good one and the price isn't too killer, although obviously I'd like them to be included in another today only!

Laugh away, no shame here, I just say what I know, I did say I could be missing something

Anyway, hope you get stuff that works well for you nightshadowUK

I still think spending lots on ram is unneccesary, but, spend you're money as you will

[NightshadowUK]

I'm not one of these money wasting types but I'm just working on the fact I'll be totally gutted if I buy my lovely new rig only to find I can't overclock as I wished because I saved £40 or so on RAM. Your help is still very much appreciated.

[specofdust]

Good man, what makes you happy is what you want

Good luck with it all, and let us know how you get on with it all

Most boards have the ram divider listed as max memory overclock or something along those lines. Its still a divider, its just worded differently, for example setting max memory overlcock to 166mhz doesnt mean thats how fast your ram runs, it means thats how fast your ram would be if HT was set to 200.
