hey Iam hopeing someone can clarify this for me, rith now i have me cpu o/ed to 4.0,445x9
my new ram i have is 1600 mhz and now i have it running at 1424 , I have my freq latch at 333 and the system mem multiplier at 320b, now i want to get my ram up at least 1600 ,so when i set the sys mem multiplier to 400b it goes to 1780 mhz wich is way to high,I tried and it wont boot at that setting, so my question is how do i raise my ram to get it close to1600? I was wthinking about this my cpu multplier is at 9 right now, what if i cheange it to 8 and then it will be 445x8 3.56, and then i can raise my fsb to 500 so 500x8=4.0 does that make sense? am i loseing any performance by dropping cpu multiplier to an 8? and then in turn by raising my fsb it will be raising my ram mhz...correct? sorry i hope you guys can understand all this lol

See this post for my settings. Instead of using 9x445fsb use 8x500fsb. Set freq latch to auto and mem multi to 3.2B. Of course you will/might have to tweak some of your voltages and refs as well, but the performance increase is worth it.

[DTV DRAGON]

thank you thats the answer i was looking for It sounded right to me when i thought about it but wanted to make sure i was on the right track lol
to what voltages would i need to change or how high should i go, also not to sound stupid but what do you mean by ref's? here is my bios now

what about my ICH I/O AND ICH CORE I have them set to normal or should i have them set to there values of 1.500 and 1.100 ? also anything else that i have set to normal?

[clo007]

Well, it has been fun!!!


I got a great deal on an X58 eVGA 3way board, a i7 920 D0, and some 1600mhz GSkill Pi sticks.

Time to sell the EP45-UD3R, q9550, and GSkill Pi 1100s.

[In-Fluence]

I've treated myself to an i7 and Gigabye X58a with 3GB of OCZ 1333 ram at work. Will only be running stock cooling there but looking forward to getting a feel for the architecture and maybe push it a little, any ideas what to expect? (I know an i7 D0 on stock cooling is criminal)!
Also just won an EP45-Extreme for £72 as well, so I'm hoping to push the CPU a little further with that, although sorting out the cooling could be a challenge .
If I do better with this board, I'll probably sell both my MIIF and UD3P and treat myself to an SSD or 2. I'm happy to settle with my 45nm setup for now and might have another stab at some 5GHz+ benching when I get the board in

Dragon, read this tread. http://www.overclock.net/intel-mothe...-ep45-ud3.html

[DeltZ]

tis funny, everytime they bring out a new bios, i try it, hoping my memory problem will be fixed...but no...let down every time

It's either motherboard or CPU memory controller, all i know is that I can't run 1200 on ram no matter what settings i do. Thought it was a ram problem, then i got OCZ blades...then i was like, oh...the same problem exactly. Can happily do 4ghz 500fsb and ram running 1000mhz, either 4gb or 8gb, but i can't do 1100 or anything on the ram regardless of FSB, strapping, CPU speed, timings, voltages etc.

[Dumaine]

Can someone possibly shed a lil light on this....with these settings I can boot into Windows, and even fiddle around here and there. Yet sometimes it freezes or some apps wont open. Im basically green at all of this yet I do have a stable overclock @3.833 24/7 (passes all of the normal stress tests that I have seen most use). Thanks for any help!!

The memory used is Gskill 1200 Tridents if that helps...

[MarcusFoX]

Sorry, my fault - the GTLs on the UD3P are just one setting called 'CPU reference', this changes with your termination voltage (VTT). By default, your CPU ref is 0.76 when VTT is also at default of 1.2v. For me, increasing CPU ref to 0.785 then increasing the VTT often gave best results, but occasionally needed to go up or down one on the CPU ref to get stable. This is different for everyone's configuration, but should still be around that region (i.e. one or two up or down from default). As for skews, increasing them as you increase FSB can yield better results at higher than ~475 FSB, seems even more crucial for benching at 530+ FSB. I found CPU being 50ps less than NB skew often gave better stability , but sometimes equal values worked better.

alright my vtt is 1.46 and ive for the termination set to .91 which is exactly what it should be at accoring to that cheat that person had made awhile ago I forget his name... trd is set to 10 so its pritty loose.. idk im out of things to try to spablize this puppy at anything lower... fun thing is my m2f is way worse with this chip.

My bad!! EP45-UD3P v1.6 and Q9550

[In-Fluence]

Are your tridents up to runing 1267MHz? Memtest may pass but prime might fail if it's near the memory's limits. Static TRead should be at least 8, 7 is too low, raising it to 10 will ease the NB a little.
See what these adjustments do and report back

agree with you In-Fluence too much speed on that rams to start testing...

[Hoss331]

+1 on the ram speed but PL 7 itself shouldnt really be an issue on 2.66D, in fact he can probably even run the extreme memory profile given enough mch and testing.

[Dumaine]

well I took the advice of the 3 of you and played with a few of the memory choices and have been able to at least get into windows with various speeds (800*8, 475*8.5 etc etc...memory 1267, 1000(4-4-4-12) and a few others.....)I just gotta get comfortable with what I want I guess then tinker with that. My main question should have been the Ref's....Im not quite sure I follow how to set them properly.

I have read some previous posts on how to calculate them and still not sure if Im doing it correctly

i PM you...

you can use for 1,2VTT .785 CPU ref and .80MCH ref then raise VTT and let other values change

for skews you gotta try 800/800/0/50 or 900/900/0/50

For the MCH i needed always 1,4 if i gonna go 1200

Cheers
Sergio

[In-Fluence]

^ those are good hints! ^

I recetly found out that I've actually got a bent pin on my UD3P which isn't raised enough to make proper contact. It was one of the many 'vcc' pins on the pinout (top right pin in the socket), and I wondered if this might be why I started getting weird stability issues. I did a little mod by 'glooping' a ball of condictive pen ink onto the corner of the CPU and hooking it up to the affected pin. This has actually helped, and am now able to use much lower VTT, plus tuning the CPU ref seems more effective too.
I guess this is all a bit late now that I'm getting an EP45-extreme. Anyone had any experience with it? My bargain find should be on it's way here soon, really looking forward to giving it a whirl.

[DTV DRAGON]

hey guys i have a prob. I ried changeing my cpu multip;ier from a 9 back down to 8 so i can work with my ram abit better, anyways I left all setting as is but changed cpu mult to 8 and mt puter did not want to boot! I even lowered the fsb so there was only a modest 3.5 o/c and still same thing just tried to boot a few times and then second bios kicked in i guess and set it all to standard 3.0 for cpu , wouldnt you think that it should at least boot up cause all i did was change that one multiplier? also my ram is rated for 1600 but do you think if i set strap to 400b then ram will be 1780 mhz would it work ? my timmings are 7,8,7,24, should i loosen them up maybe? or is 1780 just way to high? also my mch core is 1.30 is that way to low for 8 gig ram and trying to get higher freq? sorry for all the questions, what i realy would like is change mult to 8 then increase fsb to 500 to get my 4.0 o/c and then the other good thing is my ram will be right at 1600!! any suggestions or hints?

This has worked on both of my Q9650's, the references I mean. I too need 1.4 MCH for over 1200. I can use 1.38 up to 1176 with Turbo enabled.

and also working perfect for my X3380

what memory are you running with it? GSkill's DDR3 of some sort?

I have some GSkill PI's 1100's that will do 1200 with 2.10V, I kinda with I would have gotten the 1200's (PC9600) but oh well.

ok I am using the ref's you suggested and sent you a ss in the email, It says its to big to post in here (might be due to my dual monitors?). I forgot to set the skews so they are still at stock settings and Prime is still running. Also dropped the memory back to 1200..will update you all in the morning prolly (if I dont go fishing....crappie time here LOL) thank you all for getting me this far..........

I wish I woulda got the PI instead of the Tridents

hey guys need your advice I just bought a EP45T-USBP3 board, and was wondering if it will be a better choice for me for o/cing etc. than my ep45t-ud3lr I have now, what i wanted the new board for was to run crossfire, but i wanted to know if it will be as good a o/cer as my current board? if so i will be starting the switch over today, just wanted to hear a few comments as its a newer board as you all know thanx
