your trfc is way too high @ that speed you should be @28 not 56
and pl7 or pl6
even thwe delays are too high

Those subtimings are awfully loose, but P45 isn't going to match the bandwidth of X38 either way.

Alright Thanks

I'll set the trfc to 28, but any lower PL and it won't post.

EDIT: I change that one down to 28, but it didn't help much? I tried lowering some more, but it froze.

give her more nb juice
i run my d9 2.02v 5-5-5-15-4-28 @ 1200mhz 500fsb pl7

[fatguy1992]

Alright I'll give that a go, also with the 5-5-5-15-4-28, what timing is the 4?

Thanks

EDIT: I got PL 7 now

PL7 isn't that important. Its when you have to go above PL8 you want to crank NB voltage. You will find you can keep PL7 maybe to around 425-440FSB, but after that for any real degree of stability you have to move to PL8 I've found on any P45.

wrong
pl7 is important
i can do pl6.5 @ 515fsb @ 440 i can do pl5 on x38 and p35
pl8 is after 510fsb in my book

Ket is right about the P45 chipset, I don't think it can do PL7@500FSB. It's usually one PL level higher than P35/X38 for the same FSB.

[radaja]

at 500fsb+ the UD3 boards with the A3 revision P45 can run two notches lower than the A2 when using 1:1 divider (pl8)instead of pl9.but on the other dividers Shiranui gen-an is right at 500 fsb using 5:6 its still pl8(at least thats as low as i could get) with the p45 chipset.

[CryptiK]

On asus P45 boards you can only use PL7 on the 3:4 and lower divider, meaning at 500FSB your ram would be at 666 MHz. P45 is not P35, you can't say because your P35 does a certain PL at a given FSB/divider a P45 can.

On a UD3P you should be able to set PL7 on say 4:5 or maybe even 5:6 (they can run PL8 on 1:1) but it would take more vNB to do it, and the performance on the UD3P's from what Ive seen is about one PL higher than Asus boards, such that Asus PL8 = Giga PL9.

[radaja]

im not saying that because my p35 can run a certain pl that my p45 can.did you read the previous post?i was just pointing out my observation concerning the p45 performance level settings.i never said anything about p35.

[Shiranui Gen-An]

I think Cryptik was referring to zsamz's post, though I could be mistaken.

Others have already said it in different ways.. but I'll chime in too. How many P45s have you used? I've used 3. All exhibit the exact same behaviour when increasing FSB, PL7 = 440FSB tops, beyond that PL8.

thats you
i seen pl7 higher than 470 on p45
i only tinkered a p5q pro for 20 min for a freind got him to 450fsb pl7
i'll get my hands on a ut p45 soon odds are i will do 500fsb pl7

I was referring to what zsamz said not you, I should have quoted him. I just meant that due to the inherent differences between the two chipsets, you cant set a P45 to the same FSB/PL settings as a P35, on any given divider, a P35 will be able to run a lower PL.

What you can set on a P45 depends on the bios and chipset revision, and how much vNB you are prepared to give it.

Its just a matter of playing around with your gear. I can run PL7 at 480 FSB / 640 MHz (3:4) without any trouble, and PL6 at 434FSB/651 MHz (2:3).

I could go higher, so if my board allowed stable ram speeds of 666MHz I'd guess it wouldn't have issues with PL7 at 500 FSB. The UT/DK P45's/UD3P's do clock ram better than my M2F so 500FSB PL7 / 666 MHz stable may well be a possibility on those boards. Someone try it

480 FSB / 640 MHz CL5, PL7, Clock Twister Moderate


434 FSB / 651 MHz CL5, PL6, Clock Twister Stronger

zsamz_ is right here!

I didn't want to share this cause it needs some tweaking, but I thought you should see it for yourself:



I saw 10k across the board at FSB 480MHz but my CPU wasn't up to it at the volts I was comfortable with giving it and it crashed before I could take a screenshot. I will try to do this again next week with one of my new kits.

the statement ket made that max pl7 was @ 440 was
just cause a user cant do it dont mean someone else cant
took me just a few min to get to 450
i think bois not mature on p45 but 1 day it will be able to do it
so far the best board i seen is the ut p45 it has as good bandwith as the ut p35

[chad]

This is the max Cl4 timings running PL8. This is a pair of Crucial Ballistix PC2-8500. Im currently testing PL9 and already got them to 1100

[GeorgeStorm]

I tihnk I know why I suddenly couldnt get 500FSB stable anymore, I was on PL6!
Im now gonna move it down to 7 and have another go at getting some nive numbers on my RAM

nice
thats on yout biostar p45 ?
maybe more juice on nb

[Ket]

I can get 10k+ across the board with PL8 @ 480FSB as well, so the point is still irrelivent. PL8 is better than PL7 on P45, same performance, higher FSB possibilities, less voltage.

and zsamz, theres plenty of ppl who posted before me to verify what I already said. You seem to completely lack the comprehension of not all hardware is created equal and some will be better than others, but on average P45 = PL8 for FSB over 440 or so.

With CL4? please show me!

I know that bandwidth would be a lot better if I used a bigger divider.

[tool_462]

Just a fun run for a "2Ghz Pi Challenge" contest at another forum. I know subtimings could be tweaked quite a bit, but this was just a quick comparison between 3-2-2-1 and 4-4-4-12 @ 1000mhz

Edit: durr...forgot to say this was with a 1GB kit of Buffalo Firestix D9GKX confirmed

[GeorgeStorm]

zsamz_
Yeah, with my Biostar, (its the only board, and the only set of RAM I have, :P)
I am now running at PL7 CAS5 at 1000mhz,
Heres an everest, (with all the programs running in the background and playing music.......
(attached)

Any tips to improve it?
Im a complete novice when it comes to memory overclocking, (or overclocking at all for that matter)
But memory overclocking is really cool, I would love to get to know how to do it WELL,
George

like i said its user related
just cause u cant do 440+ pl7 dont mean others cant
and again you wrong there is a difference pl7 to pl8 in bandwidth


george:you need to see how high you can clock your ram try 2.1v

[GeorgeStorm]

Now now, no need to argue, you both have your respective views, and both of you can get high bandwidth numbers, so instead of argueing, teach me how to!
I just upped the FSB to 420, and gained atleast 100 on copy read and write,
Would it be better to run it as it is, or at 480 FSb and 960mhz RAM?
Although, im trying to not have too high and multi, so I actually use the speedstep tech, might aswell save power when its not being used

Thanks

some people just cant say when they wrong

get as high fsb as you can
put a fan on nb go @ least 1.4 to help ram
