A little OC advice please

Lelisevis · Jan 16, 2007, 12:08 AM

Ok thinking caps on overclockers. First im gonna give a little run down of what im running then you can help me out as my maths is terrible.

Ok stock im running with
AMD 5200+ @ 2600mhz 1.3v 200x13
Abit AN9 Fatality SLi HT Auto (5) @ 1000mhz
2 GB Geil Ultra DDR2 PC6400 400 (800) @ 2.1V 4-4-4-12 2T
BFG 8800GTS 500/800
3DMark06 8200

Now i've done a little crude overclocking that runs 100% stable. Gonna list what it's at then what I did to get it. Just need your help Fine tuning.

AMD 5200+ 3003mhz 1.35v 230x13 Idle 24C Load 45C Slow fan speed (silent)
Abit AN9 Fatality SLi HT 4 @ 923.5mhz
2GB Geil Ultra DDR2 PC5300 375.2 (750.4) @ 2.1V 4-4-4-12 2T
BFG 8800GTS 600/900
3DMark06 9490
5 Hours/ 10 passes Memtest86+ and 2 hours Orthos

Now then i'm more than happy with the graphics card so don't worry about that however i'd like to maximize my HT and Ram. Now then the catch the overclock im looking to run is 3GHZ on the processor however I'm pretty rubbish with dividers and am running the stock X13 with decreased Ram speed and HT link. What I need is a divider that will run the Ram closer to it's stated 800mhz without exceeding 3ghz on the processor and 1000mhz on the HT.

Many thanks Lel

Hmmm found this little table if it helps

CPU Multiplier DDR400 DDR533 DDR667 DDR800
4 5 5 5 5
5 5 5 5 5
6 6 5 5 5
7 7 6 5 5
8 8 6 5 5
9 9 7 6 5
10 10 8 6 5
11 11 9 7 6
12 12 9 8 6
13 13 10 8 7
14 14 11 9 7
15 15 12 9 8

Honestly im not being funny but I have total mental block when it comes to numbers. I look at them as shapes without taking in what they mean. It's totally weird.

Edit: Apologies lost the formatting on the table

The LTD is multiplier between 1x and 5x, which is multiplied by the HTT to give a HT frequency. Usually you can set this to the highest one which will give you an HT frequency of below 1000 MHz. With an HTT of 230, this would be x4, which you already have set.

Someone correct me if I'm wrong on the following, I have little experience with AM2 rigs.
Memory dividers are actually a whole number divider of your total cpu speed. I think there should be options for 400, 533, 667, and 800, you'd have it set at 667, right? 667 corresponds to a divider of 8 from your total clockspeed. So from a total clockspeed of 3000, there's no way (no whole number divider) for you to get any closer to 800 then you are already.

Your best bet is probably to leave those clockspeeds, and see if you can tighten the timings on the ram at all.

It's all getting a bit confusing aint it. I kinda see what you mean with the dividers etc. I can't remember it being this difficult with my Athlon 64 3200+ which happily sat at 2.5ghz all day long with a few minor Bios changes. Either technology is advancing to fast or im getting old LOL. Tried that nTune today out of curiousity and whoever programmed that wants shot. After 3 hours of tweaking lock-ups and bluescreens it gave me some totally random numbers and wouldnt pass 6 seconds of Orthos. It even overclocked my PCI-E bus by 58% from 2500mhz to about 3750mhz

Thanks for your input gonna sit with my pencil and paper and see what I can come up with. Keep your suggestions or experiences coming people.

Zelig · Jan 16, 2007, 01:05 AM

Heheh, yeah, ntune isn't the best of programs.

There's some charts I just found with DDR2 ram speeds, those might help.

BWX · Jan 16, 2007, 01:10 AM

230x13

Can you run that chip with a lower multiplier? It seems if you could, and your mobo could handle it, you could get your ram speed up and your HT up closer to default speeds while still keeping CPU speed reasonable..

Also- doesn't you ram run at 1T? That makes a difference in performance.. maybe it doesn't though, I run DDR1 so I am not sure if DDR2 does run 1T or not.

check that out...
http://math.gogar.com/athlon64.cgi

edit- I've never tried it, but I think with even a "locked" CPU, you can run it at a lower multiplier, but nit a higher one. I think I read that somewhere.. Maybe try it at 12 and see if it boots. If not, maybe try a different lower multiplier until you've ruled them all out of not working.

BWX · Jan 16, 2007, 01:46 AM

I plugged in some numbers-

Neshi · Jan 16, 2007, 06:44 AM

i got THE site for you...
this is really ideal. Just click on the numbers and it adjust everything as it should be and you will get all the results and can finetune it in every way you want.
this is the one!

C47 · Jan 16, 2007, 06:53 AM

i wrote a guide ....hope it helps look in the oc forum

Lelisevis · Jan 16, 2007, 11:14 AM

Thankyou very much for your contributions. I'm going to have a look through the information you've gave me and I have a good 5 hours in front of me to put it in practice. I'll be back soon let you know how I got on.

Zelig · Jan 16, 2007, 11:28 AM

Erm, guys, I don't think the calculators you posted work too well for him, other than to perhaps help with understanding, since they're all for DDR1 only.

Lelisevis · Jan 16, 2007, 04:32 PM

It's ok Zelig I picked up on the calculator thing straight away. It's a bit odd really it's like no body has bought into the X2/DDR2 overclocking thing or at least not as much as the original Athlons.

Anyway after a good 5 hours of testing I have formulated a conclusion. My original crude overclock is about as good and stable as it gets. Can't really complain when a single card GTS now gets just over 9,500 on 3Dmark '06 and 14500 on 3dmark 05. Whole rig is whisper quiet too.

Now running a 100% stable 3GHZ. Iv'e no doubt it will run a whole lot quicker in fact I know I still have quite a bit of headroom on the GTS and I temporarily dropped the memory and HT to hit 3.25 ghz but I need something that will run risk free 24/7.

BWX · Jan 18, 2007, 06:12 AM

Yeah I was thinking someone that actually had a similar system to yours (DDR2) would chime in and maybe give you some things to try. Those sites do give you an idea of how the divisors work and whatnot. Sometimes it is your first instinct that is right though. That's what happened to me with my system when going from Nforce 2 to Nforce 4 based system. I just read up on a few things, tried some settings, and they seemed to be about the most stable and fastest it would run.

That might be what you have done.. but you might find you can get a little more out if it, hard to say.

Dont feel bad man....whan it comes to RAM I'm lost as a fart in a whirlwind too.I wished some of these old pros would give a little class on OCing RAM.
