Yesterday, I manage to get my hands on a new Cooler Master GeminII w/ 2x120mm Icute fans.

They aren't the best fans around but very reasonably priced and produces better air flow

compared to the Cooler Master fans.

I had to remove everything on my small tiny case to fit the GeminII and at the same time

manage to tidy up the cables. The base of the GeminII looks flat and I was very indecisive

on whether I should lap it. After thinking for a while, I chose not to lap it (and now I

regret)

Once I got everything ready, I powered on the system. Windows booted fine and idle temp was

at 24C-26C. I immediately ran Orthos (Small FFT) and load temp went all the way to 54C-56C

(Vcore @ 1.3875). Well, a very good improvement from the stock cooler which normally gives

me around 65C-67C.

The fans are now a nuisance because they produce terrible noise and bumping the Vcore to

1.4125V and running Orthos (Small FFT) resulted a load temp of 60C-62C under a 25C air

conditioned room.

I'm not sure if these temps are good but all are reported by Core Temp 0.95 and cross

checked with Everest - same results. I'm using MX2 thermal paste and please also share your cooling results with this GeminII.

claw. there's a Gemin thread @ air cooling already.

whats ur max OC now?

Hm.. that was at 405 ?

kucingfight, I'm trying 408x8 now (running Orthos small FFT). I'll check out the GeminII thread but I thought different motherboard reads temp differently? Things has changed?

wodenus, yeah was at 405FSB. I'm now with my side panel opened at it's only 56C load.

guess u've got a golden chip tat does >400.

juz a comparison here, gemin with 2X 120mm CM case fans, 28C (at least tats what i set on the air cond controller) , full load with Folding SMP , 48C. Speed as in my sig. enclosed with CM elite 330

kucingfight, looks like you've got much better temps than me Did you try Orthos? I notice it stresses the CPU even more.

I'm running Orthos more than 400FSB but it isn't stable yet and adding more Vcore might be required.

WARGH!! im so frustrated !! why cant my f*cking e4300 cant even boot at 212x6!!! before this im on an athlon 3000 and ive managed to oc it from 1.8 to 2.6 stock fan.....
these are my screenshots from BIOS... pleaseeeee tell me whats the prob
anotha thing how to chipset of ram, does it effect anything

[attachmentid=350291]
I just finished a game of dota, had Orthos running on the background at 406x8 (1.4125V)
I'd be happy to hit 3.3Ghz at least

Have you tried blend ? and maybe a few hours of Orthos ?

Try removing the two HDs that aren't the main ones... long shot but hey what do you have to lose ?

Well I'm running 410FSB now.. it's not stable either but then again my cooler cost Rm45 I can probably do 415 but then it gets really unstable (crashes and stuff.) Yup if you push vCore and vDimm you can get it to stabliize... but you have to take care of the heat.

wah, wanna OC but remove hdisk?? not so practical.

Maybe not enough power... well he's tried everything else, might as well right ?

set PCIE from auto to 100

and change the multi from 6 to a higher number or something, maybe ur processor dislikes low multi

Try this:
Raise multi to 7 and ramp the FSB to 333 now, just try it after changing PCIE to 100, and dont touch the volts for now ( coz some ddr2 chips dislike low speeds at high CAS )

not much point running it more then 1:1 fsb, due to the bottleneck the NB creates

try to up d vfsb & vmch by a notch bro, u ain't need to lower ya multi while ur just runnin 2xx fsb.



some if not all kvr can't do tight timin even at low frequency as they were binned at CL5, so while they can do higher frequency with same or slightly looser timin, why not? most e21x0 chip can't really do fsb > 400 (or need lotsa juice in my case), that's d thing drive me to run my ram @ higher speed.

wodenus, I'll try running blend tonight but blend normally passes quite easily compared to small FFT.

At this point in time, 405 x 8 @ 1.40625 is stable (ran small FFT for 3-4 hours). How much Vcore do you need to run at 410?

x6 multiplier runs at stock vCore. x8 needs somewhere between 1.45 and 1.475... tried both and only 1.475 works.. I don't have A/C so my ambient is probably at least 10C higher than yours. AC is great for cooling heatsinks, so you may be able to manage lower.

wow, you all have a great clocker with u... mine only manage a 8*400 with 1.485v... load temp at ~71'C in aircond room somemore...

Thanks wodenus. I'm already around 58C load (Small FFT) with 405 x 8 @ 1.40625V and I tried to do 410 x 8 but unstable because it needs a lot more voltage than that Full load temps might be a lot higher too but I'll try it out tonight and hopefully I can get it going.

I guess it makes a lot of sense to get a phase change these days because if so, cooling would never be an issue (but $$$ is) - lol.

ah_khoo, my chip manage to do 400 x 8 @ 1.3875V so perhaps you wan to try lower your voltage and see if it works? Mine is M0 tho' and opening the side panel of your case might help cool things down a bit (assuming you are using those normal mini tower casings).

Bro, I have a mid tower with me, but my cooler is of silent type, so performance wise it's not so good. Thou' we are having same "M0" steepin but the batch is diff, mine is SLA93 if I'm not mistaken, not as good as yas obviously. Neway, I'm hepi enuf with 3.0GHz. For that I need 1.39v. it could be d chip is lousy or my board is not "kick" enuf for d chip, but I really doubt d latter as ppl achieved good oc with d board.

I thought batch doesn't make much of a difference these days? In fact I didn't pick the CPU so it was by luck but it still needs quite a bit of voltage to hit 3.3Ghz

Er.. unless the Intel site is wrong, SLA93 is the only batch with M0.

Apparently did with this one. max TCase is different on the two steppings.

Yea if I used your setup, I'd get maybe 68C on 405, still way too close to maximum. So phase-change is probably the only way to go now. Now if he'd only hurry up and settle his stuff

wodenus, a good idea would be to get a cascade and sell your phase change to me at 50% off

just finish setup my dad's new pc...

btw, which bios is suitable for P35-DS3 v2.2... and also, is that we need to press any key to show the hidden option in the bios?

at main menu, press ctrl + f1 bro...

then go to the MIA submenu, u'll see all d sub timings for d ram...

LOL... if I get it, when I get it

my bad, i thought one steppin can have many batches...

No worries ah_khoo, every CPU is different even it's from the same batch anyway

What's sad though is that not a lot of people make extreme coolers. Should be more people, it's sad to see FSBs above 400 and not be able to run them well

thanks bro

many new option in the bios compare to the amd platform... have to spend some time to play with it....

btw, currently prime 429x7 @ 3GHz stock vcore & ram 1:1 429 @ 4-4-4-12, 2.0v ( is this voltage high for this speed and timing? )

[attachmentid=350670]

p/s: I noticed a weird problem with this P35-DS3. when the pc is boot up, the power LED is on for a while and then become no light. Anyone face the same problem?

still ok but definately can go higher in MHz...

What RAM are you using? Those timings look great at 429FSB

Well.. he's got a 6550... there's something to be said for a x7 multiplier

What's 6550?
Anyway, I manage to achieve 3.3Ghz today The load temps are now in the 60's (not a good thing).
Btw, the softwares in Windows doesn't seem to report the Vcore I set in the BIOS. Is it normal or there's something wrong with mine?

[attachmentid=350854]

E6550.. it's a processor. how did you manage that ? what RAM are you using ? and the Vcore thing, yea that happens, not sure why though. What voltage levels did you set for the RAM ? and where's a good source of MX2 ?

http://processorfinder.intel.com/details.aspx?sspec=sla9x

sigh.. sometimes I wish I had A/C

hi i'm a noob here. can someone please explain to me what it means when my gigabyte 945 mobo can support FSB1333 Cpus through Oc?
i'm planning to buy a E6750 will it have issue with my GPU and my 667ddr2 ram and FSB1066 mobo but able to OC to 1333?

Thanks wodenus. I was curious what type of RAM is he using to do 429 1:1 with those tight timings.

MX2 can be bought from Robyncom in Imbi. I have crappy RAM so I need 2.15V (as shown in Everest) to run at 413Mhz. The Vcore is also substantially high +/- 1.43V. I left it running the whole night and happily see it stable this morning

I'll set my journey to hit 3.4Ghz now.

He's using the 10th anni.

Previously my crucial ballistix DDR2-800 can go 4-4-4-4 @ 950mhz @ 2.1v stable....

Holy smokes - this is so much better than my KVR's
Of course, these Crucial's costs a lot more.

Of course.. heh if you think yours is high... I need 1.475 here to run at 410.. most of it is probably heat makes a lot of sense I guess less heat = more efficiency = less voltage needed. Yea you get what you pay for I guess.. I'm using a 350W rated power supply that cost Rm100, it's powering a E2140 at 410 on a fan that cost Rm45, and a 8600GTS at 700/1100, and a HD, and a DVD-RW, and a floppy...

Anyway good luck.. I don't have a 2.15v setting in the BIOS and even if I did, they probably wouldn't run. I can boot at 413 using the "auto" settings but it's not stable

wodenus, if there are too much heat, it'll contribute to instability and that might be a reason why it's limiting your OC. Btw, I'm using a RM100 PSU and does the job well too It's an overkill to invest so much on a PSU for a small system like mine.

I don't have 2.15V either but I set it at +0.5V in the BIOS and 2.15V is what Everest reports.

Wow. I only went up to +0.4v and already my hands were shaking lol goodness what voltage did you set for the proc in the BIOS ? you have Hynix RAM right ?

Any luck with 3.4 GHz ?

I set the Vcore to 1.4375 (or somewhere near that, it's 1.43xx - can't remember well ) in the BIOS but software reports differently in Windows (as usual).

Don't worry about upping your Vdimm and from my years of experience, the RAM is one of the most-difficult-to-die component in your whole PC Plus, the chips are all in Tiny BGA type these days so makes it a lot better, less heaty. If you're worried, put some fans to blow on it.

I have Hynix Rev. E (don't know if A is better?). Mr. Catfight's RAM is a lot better than mine.

bro, your P35-DS3 is rev1.0 or 2.0 ? the vdroop problem really worse... I set 1.3625v but it is still 1.332v.

Rev 1.0. Yup, the vdroop is "normal" for our budget mobos...... I've heard that the P35-DQ6 doesn't have much vdroop at all.... of course, the price is also nice.....

For mine, vcore bios 1.425v, CPUz in windows 1.39v, and 1.36v load.....

Oh, just remember that software voltage readings are notoriously inaccurate....

what about the vdimm? to get 2.0v, I need to set 2.2v in bios... last time you said your ram can run stable 950 @ 4-4-4, 2.2v... is it set in bios 2.2v or the bios reading is 2.2v ( i mean you set higher value to get 2.2v ).. btw, which bios you using now?

If set 2.2v in Bios, will show as 2.2v in Easytune5. Try using Easytune5 to see the vdimm.

My rams was stable 4-4-4-4 (not 4-4-4-8!! ) @ 2.1v (not 2.2v ) @ 950mhz.....

easytune 5 can check the vdimm reading?

[attachmentid=351456]

the vcore2 is referring to the vdimm, same as the bios reading and I have to set 2.2v to get this reading.

Weird. I'm using Speedfan 4.32 and it is showing vdimm instead of vcore2. And it is showing correct vdimm settings too, which is 2.1v.

The same reading is on Easytune5. What does Easytune5 say about your vdimm?

erm...kinda weird... which bios you using now?

Since I bought my mobo, I never upgraded the bios yet. Waiting for bios that supports penryn..... Now using F3...
