Any specific changes with the new bios that you know of?

not quite sure what they changed

xxxxxxxxxxxxxx

good lookin out honda

My cpu liked 704 better.

"Note - Uncore setting will now scale with BCLK settings when set to Auto. Manual settings will be required when running BCLKs over 220 to ensure stability and improved BCLK rates.

Note - LN2 Modes might need to be adjusted to improve cold clocking capabilities. Auto = LN2 mode 2, setting to LN2 Mode 1 will result in potentially better overclocking below -140C. This is dependent upon CPU quality and cooling. "

Wish I had one that would get that cold. On my second GT now both 3003B and 3005F CBugged around -110 to -113 I can barely bench at those temps.

Will have to try a 3rd time :thumbdown:

did you try only 2 sticks of ram?

cb is somehow affected by ram....

ram voltage.....steponz is using 1.8v+ on his gtx2....lmao...it seems to help
ram channels....we used channel 2 and channel 3...and it sorta removes cb

Yep I tried 1x2x&3x no luck ram doesn't help my CB only my CBB. Tried all BIOSes too.

I don't wanna kill my good old i5 ram's (GSkill perfect storm) w/ 1.9vdimm they are rare I might try with my new sticks.

After a certain vdimm I'm sure they will throw errors.

we tried slot 2 and slot 3.(4gb)...no cb

Will give that a shot only tried 1&2... (closest to the cpu and the middle slot).

Does S.pi32m lose a lot of performance from triple channel to dual channel?

yes...

sp32m creates large files....it utilizes big big ram...

if you check moa eu finals..they onlly had 3gb..and their results were bad...


i'll try 12gb for sp32 :D

So I can't really try the dual channel (cb/cbb trick) then if I want to go after spi32m...

yes the cb trick was more for 3d runs...

for sp32m you'll have to disable the other cores...and prolly play with ram ref voltages...

Not true, not true. When we use maxmem we are limiting the amount of memory windows can use. There was some discussion about densities on DDR3 and 2GB just seems to be the sweet spot just like 1GB was for DDR2. I'm no memory expert though and only understood a sliver of that conversation. What I do know is that 12gb is gonna give you poop timings and mhz vs running 6GB due to IMC stress. If what you said was true about volume of memory XP 32-bit and 2003 server 32-bit wouldn't be the choice for super pi. ;)

You can, but you are gonna loose some efficiency. From some very very limited dual channel testing I found that you loose ~400-800k pp (I think these #'s are right.) going from triple to dual channel. That is with the same exact uncore though. One other reason to go dual channel, or give it a try atleast, is to take some stress off the IMC and let the uncore run loose. You may be able to gain several 100mhz by dropping a channel which could make up for the lost performance product and then some. Look at Gutterz's i7 960 runs. Those were all in dual channel. He just made up for it with tweaking and retarded uncore speeds. :clapping:



Do you have any links explaining ram ref volts? I have yet to find anything, but honestly haven't searched too much (yet). It's just that I've never seen it mentioned anywhere before. I was about to ask about this since the option is there on the UD6 and was wondering for a good starting point.

you can control how much xp need for memory. but you can't control how cpu address the memory.

so its 6gb vs 12gb :D

damn todo list is growing

You pick the timings, OS, tweaks, and all the random mhz's. I'll run 6GB and you run 12GB. It will be within margin of error I'm betting. That is if you pick a mhz and timings that you can run with all the dimm slots populated. This would make more since if we were arguing about 3x4GB vs 3x2Gb that are super bin IC's. Care to explain more about the cpu memory addressing vs windows? I just don't see how the CPU can/will address more than windows says to once you are in the operating system?


Honda what about vdimm ref volts? Do you have any data about those? Is there a starting point like with gtl's and such?

ill test it myself...that way there is not much error comparing data....i mean i could install xp in 10minutes and tweak a little....then run sp32 with 6gb and 12gb....

I'm just bustin' chops and making friendly competition man. Hell I hope you are right and we find another advantage as a team for super pi. I still challenge you to a dual though :D

we still have pifast challenge :D

Shoot that's not even a challenge. I'm just giving you guys time before I break your morale. :P

what morale? i call it...a todo list... :D

weekend pifast for sure..just so i'll be done with it

im dieing to get my 980x back :(

Damn ! My cpu died today on R3E :(
1.68 vtt and 2.2 vdimm :p :)

Suckos man. May it rest in piece. Now lets hope you get one of those killer CPU's back from RMA dept. :thumbsup:

sofos1990

is the high vdimm the trick to push the cb? or push the imc to work better?

i know someone doing 1.5vtt with 2vdimm but didn't help much...

depends the cpu
I was trying to bench 1M at 6050 but always failed so I decided to push vtt and vdimm . I set vtt at 1.55V and vdimm at 1.91V . Cpu scaled well at least I could run 1M at 6020 so I pushed the voltages a little more ( 1.68vtt and 2.2 vdimm ) but no change . There is a weird situation with Gulftowns and 1M that's why I was pushing the voltages .
Dunno if it's the trick to push the cb at lower temps cause my chip was cb-free but with dual channel, triple channel for me was the same . Though many guys push vtt and vdimm to avoid cb with triple channel dunno if it really helps.

thanks sofos alittle info goes a long ways

Hey guys, my first post, just stopped in to check out your Forum, I have seen some of you at XS and thought I would have a look around. Very nice and informative place.:thumbsup:

Welcome to the forum Nub :thumbsup:

Thank you.

good to see you here nub! :)

Thank you Splave. A very nice forum you guys have here.

woooot Nub in the house!!!

welcome here bud....

OPB says LN2 mode 2 for colder than -135 bloomfield, overclocking mode 1 for higher uncore and mem speed

Welcome Nub my friend! I'm glad you found your way to a house that only care about Overclocking and helping others!

thanks......saving into my 980x tweak blog :D

Thank you everyone for the warm welcome! Glad to have found this also Elano.

i am stuck at 215 bclk with my 920do. the chip is stable on my other board at 227x21 ht disabled and boot at 231 easy. only way to go up is using slow mode on the re3, but i need it for 3d. has anyone had any luck with bloomfield on this board?

^ Nub check this post, this guy got up to 269blck on the 920.

Worth asking him for some BIOS templates:

http://www.xtremesystems.org/forums/...75#post4402475

above 220blcks you need subzero....

He stated he was booting 231 on H2O with his Gigabyte so I believe it would be doable on water on the R3X too?.
