Questions on oc'ing

[rizzo]

Thats a very good score. Check the thread out superpi scores

Can a bios update make your ram not compatible with tight timings?

No but it can make itself(mb) not compatable with tight timings. Your mem will run at rated speeds/timings(most times) but the mb/mem controller decides if you can boot with said timmings. From your pi score it seems your running good. What multi did you use for that run 8?

What multi did you use for that run 8?
What do you mean?

 

[rizzo]

Multiplier. You said you had it @ 400 so i wanted to know what your cpu speed was. Fastest i got in pi is 17.297 and that was oc'd to 3359.00.

 

[ntdouglas]

Oh, ok. I was at 400 fsb 8 multi=3.2g. Ram at 2.5 divider ddr2 1000.
I know you say 1:1 on ram is best but I just want to see how high I can go with ram and f9 bios. I'm fascinated with ocing ram for some reason. Maybe because it is overclocking ram and I certainly paid out the ass for it. I'm starting to think my goal is 500 fsb multi7=3.5g and 1:1 on ram for ddr2 1000. How do you lower res in xnview to post in tpu? Max jpeg for tpu I think is 195. I keep getting error trying to upload in tpu "215 kb exceeded max 195 kb, could not upload."
for it. 15.5super pi score. 410 fsb 8 multi 3.28g and 2.5 divider on ram ddr2 1025.

 

[rizzo]

Nothing wrong with using a divider. Most go 1:1 and i do it because i've only got 7 multy so my mem gets fairly high with the bus. I'm curious how they do (pi) with and without divider. I capture with xnview and then edit it in photoshop. You just need to compress it. I think the limit on file size is a new thing because i've posted plenty of others with no problems.

 

[ntdouglas]

Ok, I will try that with xnview. Do you know the default voltages on the fsb and mch? Mine are at auto and theres no figures. Gigabyte tech is useless. I called and asked them and they said its not company policy to give out that information. What the @#!%. I just ask because mushkin tests all there ram with 1.55v on mch and 1.20-1.30 on fsb. I hit a wall last night at 420 fsb 8 multi and 2.5 on ram for ddr2 1050. If my mch defaults to say 1.40v
I was going to try 1.55v.

 

[rizzo]

Default mch is 1.25(per everest) Ive been doing more reading on the ds3 and mch seems to have a pretty big impact for higher clocks. The info is kinda old so i'm not sure if it's still accurate. Most say fsb voltage yield no better oc. If you plan on jacking up mch on a regular basis you might want to invest in some active cooling. The high bus speeds heat it up pretty good and then adding volts will kick it up higher. Mine with active cooling/no extra volts & oc to 3.255 ran at about 43 to 45c. I use my case lcd & thermal sensor wedged partially under the heatsink(not between chip/heatsink)to read the temps.

 

[ntdouglas]

So are you going to adjust to 1.55v like mushkin told me to do? I'm now going in your direction with ocing. I hit a wall again trying to get well over 1000mhz on ram. I'm gonna try 1:1 on ram and go higher on fsb. Right now I'm at 475 fsb and ddr2 950. I've got orthos running right now while I'm at work. Hopefully I won't come home to errors. Also, I dumped
f9 again. My machine was starting to boot without video, figured it was instability. Took it back to stock settings and it still did it. For some reason f9 is a piece of shit on my computer.

 

[rizzo]

Yeah, i tried highest mch and i think 1.4 vcore to boot @ 482. It booted and ran windows fine but could'nt run pi so 3359 is my highest stable oc. Speaking of bios (f10 is my fav) have you been using the f11/f12 save/load bios options? It makes it nice you can store i think 10 of your bios's so when you have a nice oc you just hit f12, name it and you can load it whenever. It makes it easy when ya have to clear cmos you'll have all your settings back in one shot. Theres an mch volt mod that seems to work if your interested and can solder. I doubt i'll do it since mch hasent helped me.

 

[ntdouglas]

Where did you hear/read ab out that f11/f12 bios thing? I never heard of it. I have my vcore on auto and its set to 1.4v. Should I manually change that down? Also, how long have you been running a high bus? What is your speed? I'm probably noobin again, I just get a little concerned about my board.

 

[rizzo]

When you go into bios on the first page look at the options at the bottom. Like where it says f10 save&exit and some other crap. If we have the same(or similar) bios you should see f11 save bios, F12 load bios or something like that.

I have my vcore on auto and its set to 1.4v. Should I manually change that down?

Yeah, for whatever speed you decide, you should adjust down as low as you can and still maintain stability. Using auto is fine to give you an idea of settings to use. I know in my case the 1.41 wasent needed for that particular oc but it booted so i could see what works(high vcore/loose ass timings on mem) for an oc i couldnt get manually.

Also, how long have you been running a high bus?

I've been running 400+ since day1 and 465 is pretty much my daily speed. As long as you're not running too hot you will be fine. If you're anything like me you'll no doubt be upgrading within a couple years anyway so the shortened lifespan effect is something you'll probably never experience. Heat is the key factor though.

dudes i have a e6600 intel duo core 2,4 ghz. How much could i increase my bus speed? right now its at 266, what do u think about 300?
How hot can i allow the core to be before it starts taking just a little damage?
but at cpu-z my multiplier is almost all the time at 6 instead of 9 doing only 1596.0 mhz, and i cant see anything in memory tab. the timing stuff i cant se anything there.

and last thing... how do i see what vent i got? and does all computers have a cpu vent?
can i buy a vent and put outside the computer cause i really dont wanna have to open my box.

Read this whole thread and you will learn an awfull lot.

i looked through this thread and saw that many ppl that has 6600 sppedstep down to 7 from 9 multiplier... why does mine go down to 6 multiplier?
and how hot can i let the cpu get ?...still need a program to show me what kinda vents i got

So you go into bios change the multi to 9 save to cmos and exit and it goes back to 6? Do yu have cpuz? Have you tried ocing? I'm not sure what vents mean. Also, give your system specs.
@rizzo. What would be the performance diff between a high fsb and say a multi of 9 and a fsb of 370 and a 2.5 divider on ram? Also, you can't get any higher than fsb of 465?

 

[rizzo]

I'm stable at 472 right now and i've booted at 498.

What would be the performance diff between a high fsb and say a multi of 9 and a fsb of 370 and a 2.5 divider on ram?

Well with a high bus speed and multy @ 9 you're overclocking everything. Bus,memory,cpu. If you go 370 and multy at 9 thats a pretty good oc and the only potential performance hit could be running your mem out of sync.

 

[ntdouglas]

Have you tried a 9 multi and 360-370 fsb with ram on 2.5 divider to compare to like 460-470 fsb with a multi of 7 and ram at 1:1? Or how about 370 fsb, 9 multi on cpu, and 1:1 on ram at 3-3-3-10. Could tight timings overtake bandwith on ram? Hmmmm

 

[rizzo]

I doubt you could boot with 3-3-3-10 on our boards. I've got the 6300 so the only multi's i have are 6/7. (imo) it's better to have looser timing to achieve a higher oc. I think it's best to find you're max stable oc and then fine tune by lowering voltages and tweaking timing.

 

[ntdouglas]

I'm bringing up the 9 multi because I still have the problem of some of my utilities aren't reporting the correct cpu speed unless I'm on a 9 multi, remember talking about that 3 or 4 pages ago? Even if I right click on my computer it reports the wrong speed. And everything is disabled in bios. I think its something with my board.

 

[beck92]

dudes i just found out that i cant change anything in my bios... isnt there any program i could use? got a e6600 intel duo 2,4ghz and dell

Like I said earlier, give your system specs so we know what you have.

There are some windows based programs but they may not support your motherboard. I cant help you with using them because I oc thru bios. Heres a couple links
Clockgen
Systool

 

[ntdouglas]

Couldn't load windows at 480 fsb on 7 multi. Rizzo, did you read my previous post on cpu speed reporting?

 

[beck92]

ok...sad news...talked with dell today. they said that they had locked my bios from changing settings.. have e6600 2,4ghz well anyway. i downloaded clockgen but i dont now what pll i should use. Any 1 have any idea how i can find wich 1 it is?

 

[rizzo]

Yeah, dont know what to tell you on that one. Could be something with the dq6's. Easy tune coretemp, everest all read mine properly @ normal 7 multy. Lemme try testing at 6x and see if i have the same problem.
