[zsamz_]

Thank you Mike,
your reply and your link is precisely what I ´ve been looking for.
I know this rule of a thump, the higher the fsb is the lower has to be the PL.

the higher fsb the higher has to be the pl

[Fritz_the_germ]

Yes, you are right. The higher the fsb the higher has to be the PL.

[zsamz_]

the board has surprised me
it will boot 500x9 1.18v and needs 1.33v to be fully stable

[thijs]

Was bored for a bit today again, so i tried some more and came up with the following. all benching done at air, batch is Q822A435
with vid of 1.0250. havent really looked in to superpi tweaking to much yet, so i suppose there is some room for improvement :

[Stefun]

Nice!

What cpu skews have you used?

[kagula323]

I have a question. Do you think that this mb will be able to run 1200MHZ with 2 kits 2x1GB of Mushkin d9 ram? One kit is Mushkin 2GB XP2-8000 Redline with 4-5-4-11 latencies (996528) (D9GKX chips) and the other one is Mushkin 2GB XP2-8500 5-5-4-12 (996535) (D9GMH). Both kits do 1200MHZ with about 2.32V set in bios on my Gigabyte EP45-UD3P but I can't get them to work togheter. Maybe my UD3P doesn't like because they are different (D9GKX and D9GMH).
I will use this mobo and memory with my E8400 cpu .
Zsamz I hope u will try and post a response to this ... because u seem to have much knoledge on DFI mobos ... I will get the mobo in about 10 days (a friend will be coming home from SUA and I asked him to grab one for me ... newegg has them for 115$ and I think that's just great price )

no way you gettin 4 stix stable on the board @ 1200
and memtest your 996535 set when i used gigagut boards it killed 4 of those

[kagula323]

Thank you zsam. Just canceled the order on the DFI LP DK P45 T2RS Plus. If that mobo can't do 4x1GB DDR2 1200 than it's no use for me. Any P45 mobo out there that would be able to do what i need that u can think of?

[kitfit1]

If you mean that the OP won't get 4 different sticks stable, that would be correct. If however you mean that he won't get 4 sticks stable at 1200, period, then i'm afraid you are wrong. As a quick look here, would confirm.

i'm sure the ut p45 can
was my mistake to buy a dk

kitfit we both know how much better the ut is

[Fritz_the_germ]

Yoh guys,
my system acts a little strange in the last days.
I am able to run prime95 (custom) for more than six hours without errors but as soon as I start up LinX 0.6.0 I am having a bluescreen after the fifth loop. First I thought there is something wrong with my memory sticks. Memtest86+ vers. 2.11, test#5, runs for more than 2 hours without errors.

Does anybody have an idea what could be wrong?
How is LinX testing the system compared to prime95?

Hello. Great result i think. Can you give us the memory settings which do you use?

[elmysterio]

Hey, where are jumper on the motherboard or bios I can change the strap to go with lower voltage ? Thanks

PUSH

[Fritz_the_germ]

O.K. I will push it.
I had a converted Rampage Formula and set my PL respecting the math. fomular in this site: http://www.anandtech.com/mb/showdoc.aspx?i=3208&p=1
But the point I am still wondering about is if I can take the AnandTech. article just for my P45 chipset. Right now I am running a fsb of 470 MHz and a PL of 8. If I lower the PL to 7 my system wouldn´t start.
If I had a X48 Chipset the formular says I could because: [tRD-(tCL/N)]>[x/N]
N= FSB-RAM-Divider => 7-(5/4)= 5.75 is greater than 2.75/(5/4)=2,2
2.75 is for fsb> 466 MHz.
I doubt that the formular works for the P45 chipset.
Does any math. fomular exist for the P45 too ?
I want to catch the math. relation between the fsb and the PL about the P45 chipset.
Is it possible to run a PL of 8 together with a fsb of 470 by increasing the vnb?
My vnb right now is 1.2950v (=1,26v real), CPU VTT is 1.23v.
Every time I do so my system wouldn´t start and I have to pull the jumper.

pl8 8 is easy even at 500fsb
x48 can do pl6-7 at 500
only 1 thing is needed more juice on nb like 1.38+ get ready for some heat if you got no fans on nb

[Fritz_the_germ]

Thank you for your reply.
That means I could try a PL of 7 by increasing the nb core up to 1.38v (and even more). I will do so.
Where is the temp. limit for nb to make the system unstable ?

temps are what you comfortable with lol
just keep em in the 40s
just dont forget to put a fan on nb

[Nick.ua]

Within the limits of summertime bench-sessions XtremeLabs.org , it was possible to subdue on motheboard DFI LanParty DK P45-T2RS PLUS the FSB in 685MHz:


http://valid.canardpc.com/show_oc.php?id=604832


Northern bridge was cooled only stock!. Memory obviously is not capable higher 1370MHz. The reserve for the further advancement is also very quite good)

In connection with problems arisen with mb, it was not possible to check up more the processor in other tests.

In general memory 1400 + and a LN2 Pot on a chipset) is necessary.
To be continued

Higher the NB voltage, lower you need to keep the temps as a rule of thumb. Voltage alone won't kill electronics, but voltage & heat make for a pretty potent destructive force

Low - Mid 40s for high FSB/tight PL latency is fine if you don't get 30+C days. The hotter your ambient temp gets the lower your NB temp will need to be to maintain stability. In constant temperature mid 40s is adequate, but with variations from day to day, you want to aim for low 40s so when you get that odd day when its warmer than usual, blue screens or hard locks won't drive you crazy or make you waste hours readjusting bios settings.

As much as I love my DFI X48 board, it doesn't like heavy temperature swings when I've adjusted every bios setting to near their limit. If I set everything up in 18-20c temps then I can run everything at its limit as long as the ambient temp doesn't go above 25c or so in my room. If it does then I get random crashes and the only solution is to back off GTLs/DLL Skews/Vrefs/PL until they stop.

I've done it so many times that now I just run my Q9550 at 8.5x400 PL8 and ~61-62ns mem latency, and other than not having to deal with occasional crashes, I don't notice that great of a difference for day to day usage compared to 450+ FSB with PL7. For benchmarks my timings/gtls and such are crappy, but I spent some time tweaking the "relaxed" settings I use day to day with Linpack and OS responsiveness and while Everest cache benchmark tells me I suck, gaming/general use tells me the complete opposite.

You can get good performance from relaxed settings if you spend the time learning them to play nice and get along with together! DFI bios adjustment is so flexible that you can pull off great performance with much lower voltage/heat/frequency cost. Just takes some patience and a keen eye for small details to help you make fine adjustments.

well i do notice a difference in daily usage fom 400-450fsb thats why i'm @ 500+ 24/7@pl7
and if need be pl6

Australia isn't very high FSB friendly for at least 6-8 months of the year. Can I go ahead and assume that Europe is a lot more forgiving and clock friendly all year round?

I've done 495MHz FSB PL=7 on P45 at ~1.45V, just needs excessive cooling.

Well, during summer it's quite hot here too, and our houses don't have air conditioning! But our winters are better than yours for sure!

[WSX]

E8400 overclocked to 4GHz, I got an 80mm fan attached to the North Bridge and the NB still hitting temps of 58c

That sounds pretty good!
Just tell me how you adjusted the CPU VTT by using the 1.45v on nb.
Did you set FSB Vref on auto, were your DRAM Timing Page on "fast, fast" and did you set "Model 3, Model 3 , Model1 ?
