I think its probably like stang said that your ref settings are off. When you switch anything in the BIOS or at least for me, you have to start all over again other wise you will have all kinds of issues. When I say all over again I mean all over again settings wise.

You have to tweak each individual setting all over again. I can just pop my head in to the BIOS not make any changes but, tell it to save the settings and my system will want to be tweaked again to get stable again. Maybe this is just me here but that is how mine acts.

I think 3.20B gives the best performance. Post a MemSet screenshot along with the SPD from it so we can see what your RAM settings are at.

So it failed Prime blend at the 896(?) size with all ram settings on auto (ridiculously loose 10-10-10-24) So i set to 7-7-7-20 and left everything else on auto and running blend again. there is a problem with the spd on this ram so i am getting the 7-7-7-20 from ocz website and forum. Below is current memset values. Thanks for your help, would love to get ram stable at 1600. I am using voltages same as in previous post.
edit: i bumped dram voltage up to 1.82, prob needs this at 1600?

Have you tried using PL8-240B? It worked fine with the G.Skill PI's well over 1200mhz.

Thanks for your tips! Setting 800/800/150/150 got things stable very fast, I could even lower vtt and vMCH and still boot at 510MHz FSB speed.
I was setting PL8 in Windows using MemSet.

Thanks again! :)

No problem mate, I think you saw my results on hwbot, it worked out.

So what's the feeling on these Drive and Skew Settings? What's ideal for the Core2Duos at high (500+) FSB?

Well when i was running 8x525 DDR3 1050 i had these set at 800/900/0/0 and that was very stable. I had instability before i changed pci express clock drive to 900.

what's up with the ud3r failing or shutting down al of a sudden as it's loading Vista????? and the sequence in which you have to hit the start button?????

do any of you guys get this, or did i just get a bum board here???? :shrug::shrug::shrug:

ps: i'm certain it didn't degrade cause it's been doing this since the first night i brought it home...

the Asrock p4i65gv did this

edit: i think if ofund the answer - it appears the memory is being set to too low a voltage everytime i reboot - didn't notice that - - oops

nothing i could do could get my faulty team xtreem 1300 stick to not bluescreen at 480mhz, and 1 good stick is only good at seeing how far it will clock for the sake of it, and my crucial fatties wont boot at its rated speed of 400mhz either, guess my board really doesnt like them.so i got some ram thats good for gaming and somewhat good for benching too, ocz flex ex 2x2gb 1200. i heard it uses an unknown type of hynix ic,s, unlike the flex 1150,s which use psc. anyone know what are the best subtimings for high clocks on this ram? if you ignore trfc it actually defaults to pretty tight timings for a 4gb kit particularly trrd of 3. timings in memset are as follows:

5-5-5-5-18-6-54-8-14-11-3-8-5-6-3120t-2t (pl8 is manually set in bios.)

so far i have tried 500mhz 5-5-5-18 2.2v its orthos stable, will try higher tomorrow.

edit: thats odd, if i set 400 fsb 4:5 divider 266 strap = no boot, 3:4 divider 400 strap = no boot regardless of fsb, yet 375 fsb 4:5 divider 266 strap boots then upping fsb to 400 with setfsb = 10 minutes orthos stable what gives? it was still error free after 10 minutes but i stopped it at that point. also every time i get back into bios after a failed reboot it comes up with the red failed overclock message, all settings i most recently put in dont change except cpu multi goes to 9. is 3:4 divider bugged?

I've read about a few disappointed people with those xtreem sticks, they're good while they last, but unless you give them some hardcore cooling they can fail quite easily, particularly with the kind of volts they're rated for. Those flex ex seem tgo do quite nicely, did you just buy those? New? Where from? Are they not rated at 6-6-6-18 like here?

I'm going to go on my 3rd hunt for 8gb of DDR1200 at the end of this month, and I'm eyeing up the tridents which are pricey but I know they perform well. There's also a couple of revisions of the G.Skill PI's (i.e. silver and newer blue versions) which cost even more, but I expect they'll perform better.
If they all fall outside my price range, then I may consider going for some flex ex instead, particularly if the price is good. My chaintech sticks will happily chug along at ~1160 (only 10MHz over stock), but no further whatsoever and I don't like being stuck on the 1:1 ratio.

In the meantime, I've been seeing what the board can do with stock volts (except vcore & vdimm), and it passed a loop of p95 blend at 480x9 last night (this is with just 1.2vtt, 1.2vmch, and 1.5pll, and a trd of 11 for now). This board still slams my MIIF in terms of voltages needed, I previously had to go for something like 1.36mch and the 1.36vtt at those kind of speeds, and I would struggle to get it stable.
I'm now testing at 489x9 to see what it takes to get 4.4GHz stable, which I think is finally on the verge with these measily volts, but it's a good point to learn what adjustments make the crucial differences when increasing fsb (rather than my previous 'stab in the dark' attempts). I just keep getting more & more impressed with this board as time goes on, all I want are some mosfet blocks, DDR1200 memory and i might be happy :rofl:.

How many of you have removed the blue "GIGABYTE" and "Ultra Durable" plates from on top the Silent-Pipe heatsinks? How hard to remove and what did you use? It looks like these would hold in heat and are only cosmetic. Taking them off would allow more air to hit the actual heatsinks correct?

Bluestang, some questions for you or anyone else that wants to chime in! I see you are running your work rig at PL8. Did you try going for 7? not stable? I have my ram stable at 1600 now and priming with trfc 60. next step will be lowering trd so any hints? did you have to up vMch to get lower trd?
Thanks again for info on straps. 3.2B seems alot more ram friendly than 2.66D was.

PL7 at 500fsb never gonna happen! I say go right for PL8. Check your Everest scores at your current PL12 and then at PL8, big difference:up:

i took them off all my boards.after you have the heatsink assembly off,just use a blow dryer to heat up the blue covers and gently pull them off.if you get them hot enough the glue will stick to the blue part and you will have an easier time cleaning the glue.:D i only took off the NB one on my last two boards.

any opinions on these while they're in stock, i figured it was time to go for some decent ram instead of the pidley 1066 i've been surviving on and wanted to do 1200..

i'm sort of limited here, so these are all i can afford now that i got the board stable...but Gigabyte seems to claim you can use up to 1300 and above for a "performance boost" and 4 gb is right about in my price range...

I know some of yous recomend the Trident and obviously the teem extreem stuff, and flex also, but would you recommend the Ripjaws or can it not even hold it's water at 1200 (stock)...:shrug:

thank you for your time, i appreciate the input:cool::cool::cool:

if you can afford it,these are the best.and will do ddr2-1300+:up:
F2-9600CL5D-4GBPI

ok, thank you for that quick response.... i'l see if i can scrape up another 40.00

cause i definitely need 4 gb this time....

i got screwed with Dominator, they sold me a dead stick and i'm stuck with 2 which could go any day now...:confused::confused::confused::confused:

EDIT: ironically, that's less than i paid for the dominator

thats just karma
you got what you deserved
too bad you cant but any of mine but anyone else can:rofl:

how come you're in this thread??? .........

EDIT: forgive me, i don't wanna get back into this...

all i was looking for is advice on memory....i figure it's time to move on....

duh i had the board
no you wont be forgiven thats karma for ya

nice mobo, pity is not for the beginner overclockers. Today I tried the 4200 1.264v "solid" the system starts even at 450x9.5 but beyond 443x9.5 not stable. Some ideas with the skew?

yes, they are rated for 1200 6-6-6-18 2.2v. they were instock at a local computer store so i snapped them up. not cheap mind you. hopefully i dont regret getting these instead of being patient and getting g.skill trident 1200 5-5-5-15 1.8v. im hoping for 1100 5-5-5-18 2.2v but i have read 1200 definitaly requires 6-6-6-18 and very little is known about subtimings and how it behaves with this board unfortunately.

they should do 5-6-5-15 1200mhz;)

i have hear they can do 1000 cas 4 so thats a possibility, im not holding my breath though. no way my board is going to do 480fsb 4:5 anytime soon and 3:4 divider 400 strap wont boot regardless of fsb so any suggestions what divider will get me there? perhaps 2:3 for 24/7 and 4:5 for benching? both on 266 strap btw. havent even tried the 2:3 divider or anything higher on this board yet.
