3576 is it !

Im agreeing with you on this comment mark.

im having problems geting high fsb on my QX, yet she'll probably dance the tango with anand's QX. :T

Wait a couple weeks for nol's test to be finished, and you should get your nice package from me. <grin>

I have almost the same setup as you coming in . We should see what the difference is in 3d marks when you have the 9450 paired with a 8800gt/8800gts.

Here's 3DMarks 06 with 3.92GHz X3350 and a 8800GTS.

 

[Markfw]

What motherboard is that, that gets to 490 fsb ?????? Or is it a lucky chip ? or ????

Wow the first one ive seen that passed 470fsb.

How does it hold on prime? Do you have any pics?


Mark im telling you my X38 has no problem holding fsb on windows bootup and operation. I can even throw a 3dmark on it. However when i run prime, we see things totally different.

Which board is this? My Maximus Formula did 472-473MHz stable and even higher but I couldn't get the CPU to run higher than 3.8xxGHz...

 

[Obsoleet]

I thought the DFI X38s were getting 555FSB from what I read on xtremesystems?

I thought hard on the DFI but decided I probably won't need 555fsb support (he didnt specify the multi) and I would've lost alot of other features I wanted like eSATA. I personally am only going to as far as stock vcore will take me, thinking 3ghz eyes closed and leave it at that till later on.

Sounds good Great time to build huh? I couldn't resist these rock bottom DDR2 prices myself. I won't be picking up an equivalent bloomfield rig for what I just paid I know that much!

 

[runawayprisoner]

Priming was done to death at 475MHz, and I resorted to OCCT for anything above 480MHz instead. Simply because it's faster, and with over 8 hours of Prime95, I failed OCCT before, so now I trust OCCT more.

http://i235.photobucket.com/al...am/PC/OCCT39stable.jpg

That's 487 stable in OCCT.

And... 500MHz validated just for the fun of it. Board is revealed as well.

Or actually, you can see my setup in my signature.

Edit:

http://www.xtremesystems.org/f...howthread.php?t=182791

And that's the WR so far. I was holding it previously with 490 benchable, but someone beat me to it. I guess I just need some volt mods on the motherboard to keep going further. vFSB limited at 1.50v and vNB limited at 1.71v is just not doing me any good.

By the way, for 475MHz, I needed way lower voltages:
vCore: 1.3125v (1.3250v just on the safe side)
vPLL: 1.58v
vFSB (VTT): 1.32v
vNB: 1.55v

487MHz required:
vCore: 1.3500v
vPLL: 1.66v
vFSB (VTT): 1.46v
vNB: 1.67v

For those interested, 475 is stable in Prime:

That was actually a 9-10h session, not a 54000h session (that's over 6 years).

 

[bryanW1995]

ok guys, watch out! my X3350 has finally arrived...overclocking is about to begin. Well, it will begin on sunday, anyway...

 

[aigomorla]

Shrug

I guess my chips perfer high Clocks with lower fsb.

On the Wolfdale i was spanking 533fsb on it.


the Yorkie is windows bootable @ 4.0 @ an insanely low Vcore. Prime is where i have problems holding. FSB i'll boot but if its not stable for me, it doesnt mean jack.

 

[dunno99]

Running my X3350/P35-DS4 at 3.6 with 1.075V (at least, that's what RealTemp is reporting). RealTemp max running Prime95 is 64/60/52/58...which is kinda weird. I lapped my TRUE120 (with NF-P12), but didn't do so for the heatspreader (which is slightly curved). I also didn't add any additional padding to the TRUE120 clamping either.

Anyone know the physical locations of the cores on the die, so I can tell how badly my heatsink is oriented?

 

[Cutthroat]

I received my Q9450 today.

And so the overclocking begins. Here's the story so far...

Using a TRUE + 2 x Noctua NF-S12 and Shin-Etsu X23 on an Asus P5K Deluxe BIOS 0809 with 2GB G-Skill DDR2-800 'HZ'.

3.2GHz passes with flying colors. Default vcore, temps are reasonable ~70C on core#1 full load OCCT.

3.6GHz would POST but Windows would crash shortly after booting. I removed 2GB of RAM because without all 4 slots filled I can push the fsb farther. Leaving in only 2GB G-Skill DDR2-800 'HZ' works great at 900MHz, VDIMM is 2.3v, Vcore 1.3v.

Temps are kinda high, maxing out with OCCT full load at 75C on core#1, while FAH max temp is 70C, ambient temps about 28C. 1hr stable with OCCT so far + 1hr of FAH, I believe this will be good as I had to bump up the vcore a lot of times before OCCT would even run for 1 min.

I'm testing some ICD7 vs Shin-Etsu X23 for the DC forum and will be lapping the CPU and TRUE in a couple of weeks. Hopefully that will help my temps.

Here's some pics of my BIOS settings in the 'Jumperfree' menu, and some benchmarks, cpuz and stuff.

Screenshot of CPU-Z, benchmarks, etc.:camera:

'Jumperfree' menu 1:camera:

'Jumperfree' menu 2:camera:

I think I'll stick at 3.6GHz for now until I can get the temps under control better. But I can tweak my memory timings in the meantime.

To be continued....

 

[runawayprisoner]

They are around the middle of the die.
And actually, the IHS may be convex or concave... or uneaven in itself. Or at least mine was. Lapping it gave a good 5C drop in temperature.

Ah, sorry, didn't specify. But mine was a bump in the middle (instead of a dent). I'm wondering if putting additional padding on my TRUE120 would make it better. Since it can still sorta twist, I'm wondering if it's keeping the temps up.

 

[runawayprisoner]

I know it's a bump in the middle. I meant that even so, the IHS (or the die surface) can still be uneaven. Padding may help, but if you want to see results... start stocking on lapping supplies. Mainly... sand papers.

GA-EP35-DS3P is my motherboard. I moved an e6300 into it to check the BIOS, sure enough it was only F2, so I upgraded it to F3 so it will recognize the q9450 I expect on Monday. I love this motherboard, Gigabyte has delivered nearly 50 different models of 965P or P35 etc and they finally seem to have it down. Very clean and simple, 5 fan headers, appears to have SPDIF out header on the motherboard. It was bought primarily for hackintosh compatibility, but I want to OC it as long as I'm here. Also really love the Centurion 590 case. And the WD 640. Unfortunately this board lacks GTL and I'm not sure it will ever offer it in future BIOS. Incidentally I really like this Coollaboratory Liquid Pro thermal "paste", though I also have some of their LiquidMetal Pads I could try.

So, just to test some limits, I was able to boot the e6300 into XP at a 485 FSB. I bumped the GMCH and the CPU voltage a tad. This was with some Transcend 1066 DDR2. Did not try dual prime, just wanted to see if the board was up to it for high FSB.

My goal is to run the q9650 at 450FSB = 3.6 Ghz.

- Is the factory northbridge passive heatsink/pipe going to cut it? Does the southbridge need any help?
- Is the Arctic Cooling Pro 7 CPU HSF going to cut it?
- Should I get 2 more 1066 AxeRAM sticks for a total of 4x 1GB sticks? Or would I be better off with 2x2GB DDR2 800... or 4x = 8GB?
- What voltages should I bump how much?

I'm having trouble believing the temperature readings I'm getting are correct. I'm using a Thermochill PA120.2 witt 4 fans @1200RPM/Swiftech Apogee/MCP655. My 3350 is running at 3.68GHz with vcore at 1.38 and at idle my temps are 55/55/49/49 cores 1 thru 4 and running the everest torture test my temps go up to 71/73 briefly. Speed fan shows the cpu temp to be 31 as well as everest but the individual cores running over 50. Could this be correct?

My Comp

 

[Markfw]

Tutto, yes that would be correct. You may be putting out too many watts for that to handle. I am not farmiliar with that unit though.

 

[Tutto]

Prior to this CPU, I was running a qx6850 @ 4GHz on the same loop and my temps never got close to 70 and surely never over. When I remove the waterblock, it looks like the thermal paste is evenly spread so I dont think I have a problem with the IHS. This CPU couldn't be putting out the same watts a 6850 does, could it? With everything set to auto and running at 2.66GHz load temps are in the 60s. I was under the impression the 45nn cpus would create less heat?

 

[tenax]

unfortunately, cpu temps with many boards with the new 45nm dualies and quads can be suspect..i'd do a google search..i.e. "board model and temperatures" sort of thing and see what you can find in regards to that. also www.xtremesystems.org has a lot of mobos for that 45nm that people have used that there are threads on.

Hi everyone. I just finished building my computer and I got the X3350 to 3.2ghz with a 400FSB and vcore 1.4v. I tried to check temperatures but Real Temps only shows one core and it always states 42C. Whats another way to find temps? As long as its below 65C its ok right? Is there a limit to how much Vcore one can increase before it becomes too much?

try core temp .97.1, that's supposed to report accurate temps.

I personally think you should lower the vcore. at 1.4 you're pumping a whole lot of voltage into your x3350 for a relatively low end OC. Is it stable at all at a lower vcore? My q9450 isn't the greatest chip, but I have it stable at 3.4ghz with with 1.184 voltage. bios setting was somewhere right under 1.250 but I guess my mobo is undervolted or something .

What do you mean you have only one core at 42C? It doesn't show four cores? or are they stuck? Please elaborate.

Also check this out here. Apparently Intel states the VID max should be 1.3625V although i've seen plenty of members go above that limit for this particular chip

I really think these chips don't like the high FSB (over 440). So I backed everything down, and my temps are much nicer, but NO OC improvement.

3576 is it !

Have you checked for fsb holes? like 6x501?

Or some of the old P965 tricks like bumping up the PCI-E to 105/110/115 to increase high fsb stability?

 

[runawayprisoner]

1.4v vCore is too overkill imo. That was enough for a 500 x 8 overclock!

 

[OLpal]

Hey Guys are the Q9450 & Q9550 retail boxed ,, coming with a decent heatsink-fan setup or do we need to replace due to inefficiency !!????
what kind of temps are ya getting with the stock cooler ???

I was thinking of playing with the just in store AMD phenom X4/9850 Black, but i chickened out !! Good Luck AMD
