Hey guys, thought id have a go at overclocking my CPU for like, the first time ever, but properly...well hopefully.

Basically, just a quick question about CPU-Z v.1.37....

On the "memory" tab, where it states the frequencey, is that an accurate measure of the RAM's speed? ie b4 the ddr is applied? Or should i be ignoring this...

Cause ive overclocked my cpu slightely, and in the Bios i have the ram to run at 400 (ie 200)...But as ive overclocked the cpu fsb a bit will this automatically highen the Ram speed?

Feedback is highly appreciated :) Thanks...

Also i mite be asking some things about overclocking! Like whats the best settings i can aim for, like is it better to have a lower CPU multiplier with a higher FSB or vise versa etc...

Thanks again!
 
This might help.

Plenty of good results there, but i'm not sure if i can post them here, google link should be ok.

Yes though you're right, memory speed increase as you up the FSB, so unless you have higher rated memory you need to switch the memory onto a divider, 333, 266, etc...

Too much to cover when its all been said before, see the google results or check out the overclocking sticky in this forum.
 
Indeed, read a fair few overclocking things over the years...

Just to clarify tho, my ram is only rated at 400mhz, its the G.Skill ZX 2GB kit ones...Ive dropped them down to 333mhz just to see if things change...Need to read up on that i guess, to see if its more "beneficial" to have lower rated memory but a higher cpu clock speed or higher memory speed but a lower cpu speed.

Thank you tho for the reply, much appreciated.
 
Hmm...im currently running the CPU at 2480ghz ish...according to cpu-z...

See, now lowering my ram to running at 133mhz, instead of the already lower 333mhz, what that not hinder performance? Or would the increase in Cpu speed be THAT beneficial that the ram speed wont get hindered? :)

Try CPU FSB 245X11. Memory FSB to 133mhz. That'll get you to 2.7ghz.

If he's new to Overclocking do you think it wise to tell to ramp it up? even without extra volts, its better reads up first. :confused:

When you start overclocking you push the FSB on the ram up with the cpu, this why you lower (the divider) because you're overclocking will slowly bring the ram upto its rated speed or as near as you can get.

Hard to explain when you don't know. The guides explain it better then i can anyway... ;)

Yeah, thought the ram did that, just had to ask really...im not a complete beginner to overclocking as such, just never practised it as much as some. :)

But indeed i shant be trying the speeds posted above yet as i believe you'll have to up the v.core to get those speeds anyways...

I just tried running everything at 235x11 and i didnt get into windows, i got bsod.

Currently in windows running it at 230x11...then the Hypertransport speed is at 4x, if that was the rite word to use initially. Making it 920, which is within the 1000 "limit".
 
Hah, indeed eh! Figured you mite have gone out or something...

Theres always tommorow :P But your probably working, pfft!

I'll post what i have done so far anyways...

Rite, currently got all voltages locked, ie ram, pci etc...

Running at 230x11, with the HT multiplyer at x4...

Its ran a few cycles of prime 95 on each core simultaniously, as well as Orthos.

However, one core seems to fail on prime 95 occasionally...not 100% sure what the reason is for this, any ideas? I dont really want to start adding extra volts through my chip as of yet, if at all, as im only on stock air cooling soon to buy a new fan etc.
 
Hey guys, thought i'd post an update...

Currently got the cpu at 2.6ghz, ~237 x 11, with the HT frequency x4...

Everything seems stable, ran Orthos for a while and it didnt spazz out, if i go above 237 Orthos fails on core one, me and Harris tried dropping the HT to x3 and upping the fsb to 237...but Core one still failed, so i'm presuming ive got just an annoying first core :P

Ah well, leaving it at 2.6Ghz and seeing how things pan out, going to soon buy a better cooler to keep temps down a tad more.
 
I've got the same RAM as you and I've overclocked it to 216 MHz (260/6 * 5). You might need to slacken the RAM timings to get higher than 2.6GHz, either that or give it more juice. If your gonna get a new cooler, you might want to consider the Arctic Cooling Freezer Pro 64, it's cheap and definately does the trick!

Hmm i guess so...

Thing is i wouldnt know what to change them to..like, at all... :(

Also i try to avoid upping voltages if possible...But yeah the freezer 64 pro is definetly an option, or ive been eyeing up the Scythe ninja / Tuniq tower...My friend mite be ridding himself of his Big typhoon soon also so even thats a possible candidate...
 
the ram isn't his problem guys, he has a weak core0 i was round his house looking into it! it's not voltage problem as 236 is fine but 237 fails i don't think 1mhz would increase the need for extra voltage! and again slackening timings won't make a difference either!
 
Hey, thought I would revive and ollllllllllllllllllllllllld thread :D


I have decided to start clocking my chip again for the hell of it :)

Currently got: 230 x 11, and then the HT at x4...Making the clock speed about 2.539 according to cpu-z.

If I go above 230mhz Orthos fails on the cpu stress test. I also have the RAM down to 200mhz currently =/ Still trying to figure out the dividers and stuff and whats best to use etc. Oh and 200mhz is the lowest my board supports. (Asus a8n-sli premium)

Anyone have any ideas on whats the best thing to do next?

Drop the Multiplier to x10? Then go from there...How about the HT setting. I'll have to keep an eye on that naturally depending on the bus speed i select.

Thanks in advance guys if you have any ideas :)
 
I ran my nov2005 4400 at:
11x240=2.64 with ocz 3200plat at 240 5,3,3,2,1T
prime stable
prime death temp =60c (typical temp under load with 3D =57c)

@ 11x245=2.7 prime death temp=50c (not useable)

@ 11x250=2.75 prime stable with water cooling + many fans LOL

I'm very sure that your board has more dividers than just 1:1 i.e. 200MHz. If you drop it down to 166MHz, then your RAM will be at 180MHz and therefore not overclocked.

The lowest bios setting i've seen is 200 Mhz...Unless an update gives you more options?

I've had the system at 258 x 10, but I think my comp froze over night...It's hard to tell, cause im having trouble getting video lately at boot with this board / graphics card...Doing my head in.

I'm currently running at 256 x 10 = 2560~ish...with the HT set to x3...

Oh and the ram's at 200mhz...should I set it to 1T as well?
 
Hey, currently got everything prime stable (Overnight) with the following:

250 x 10 = about 2500 Mhz

Ht multi is at x 4 making the frequency about 1000 or just over according to Cpu-Z....Is this ok?

My RAM is also set to 333Mhz in the bios, running at 1T. So in cpu-z its saying its running at 208~Mhz...Is this ok for 3200 ram?

I'm trying to get a good balance on the ram and cpu speeds, as i dont think ill be able to clock this much more =/
 
Hi,
Just going through the same process myself (thread in the CPU forum). I think I might have finally got my x2 4400 stable at stock....issues with my Corsair RAM and Mobo compatibility.
Just curious what sort of temps (Idle/Load) are you getting at 2.5Ghz ?
Cheers.
