Trying to get ratios to reach 1:1

post #1 of 13
Thread Starter 
Hi all,

I am running a P4 630 3.0GHz @ 3.8GHz (see attached gif image). My ratio is at 2:1. Any suggestions as to how I could maintain my speed at 3.8GHz and have a ratio of 1:1 ? Thanks.

Set all your settings at default. Then set your FSB to 266 which brings it into spec at 4.0GHz. Your ram should now default to 1:1 at 533 X 2 Dual Channel 1066MHz.

I would look to a better cooling device though.

Actually, you're at a 1:1 ratio.

With nForce 4 chipset, that's the way it's red by CPU-Z, thanks to hypertransport you'll never see the memory at its full (current) speed but always in half.
So, 126(x2=252)fsb which is equal to the fsb of your CPU of 253fsb. Anyhow, that's how nForce 4 read memory, but you're actually at a 1:1 ratio.

All nForce 4 motherboards are that way, by all I mean the IE. So, nothing to panic about it.

Good news. Thanks for the heads up.

I still would move to the 1066fsb though.

Thanks for the heads up Nasgul. I i tried keeping all clock speeds at 1:1 via calculations when I lowered or upped them but I kept getting 2:1. Looks like I have to live it it . The more important question would be, how is my performance affected? Is my fsb really at 2:1 of the memory or is it performing like a 1:1 ? I'm happy with my speeds. And stability is not an issue, passed OCCT 30mins test and 8hrs with Prime95 on blend with no errors.

I'm experimented with both FSB and ram at 266 and the PC did boot up and I was running at 4.0. However, I couldn't boot Windows(stopped halfway while starting windows). I upped Vcore to 1.6 and Vdimm to 2.15. Suppose I move into better cooling, will I be able to bring those voltages even higher? P4 3.0 @ 4.0 doesn't sound like a bad idea IF its stable

P/S I noticed that Nforce chipsets run really hot, so does the southbridge as well. Idle at 43deg celcius and Max at 48deg celcius. I did a custom twin active cooling mod on northbridge but this was the best I could get. Are these values worrying?

You're running a 1:1 ratio but just like I said, nForce 4 and hypertransport doen'st allow for the memory to be red correctly. If you were to run DDR667 in an Intel system it would show up as 333mhz but in yours, it would as 166fsb which is correct but misred by CPU-Z.

Believe me, you're not the only one that's been concerned about that issue. It's just normal and nothing to worry about it.

Whatever RAM speed you get, just multiply it by two and that's your actuall (corrrect) speed, so if you do a 260fsb for CPU then RAM should read 130mhz on a 1:1 ratio. There are other ratios that I haven't seen lately but they're in pretty high number ratios, like 16:xx....something like that.

On a 2:3 ratio would be: 200:133mhz and on a 3:5 ratio would be 200:166. Despite the lower number on the right side of the column, that ram will be running at full rated speed.

I've taken four 630's to 4.0GHz on the 1066fsb with default voltages but all of them have been on an Intel platform so possibly the Nforce does not work as well for this move.

Thanks for the further explanation Nasgul. At last I'm contented at having a ratio of 1:1 eventhough its not CPU-Z verified. These nforce chipsets are quite a perculiar beed .

I agree with Ropey, nforce might not be able to bring it up to 4.0Ghz easily. I should consider intels as they do run cooler as well.

I wonder if there's anyone out there who've reached 4.0 (stock 3.0) with an Nforce chipset. Could it be my CPU's revision (i.e N0) that's limiting me?

I've seen a couple of people hitting 4.0ghz on the nForce 4 (IE) board. But both have been with the Pentium D 805 and a 940, I haven't seen anyone else with any other CPU. So it's either the 533fsb CPU or a 65nm in the 3.2ghz and above range to hit a 4.0ghz speed.

As for the chipset getting very hot, that's also common despite the huge heat-sink. Maybe you could fix it with attaching a fan to it ot get a replacement HSF for it.

Thanks for the info Nasgul, i think i'll invest in some good cooling before moving on . I'm at 3.81 at the moment and its fast enough

Just getting out of topic here. Sometimes, I get the blue screen on windows but I passed OCCT and prime95(blend) for 8 hours. I know it must be the rams but my Vdimm is already at 2.15volts. Could this high voltage cause the rams to fail sometimes? On the other hand, I'm starting to suspect that 1:1 ratio isn't good for me as i think 3:4 (this reading was from CPUz fsb at 200 and ram at 266) was the default ratio when I was running at 3.0GHz. Is 1:1 guaranteed to be the best ratio or would it be better to run at the default of 3:4
