I don't know. But I am sure you'll want to be saving for the 8600 Ultra and not that X1950 Pro. Will be the same price, but DX10 and probably a much better performer.

9x334, 1.45 vcore (system wont POST with 333x9 for some reason)

Your vcore seems pretty high. On my Gigabyte S3 I only need 1.35ish to run 334 stable. Maybe it's your mobo?

Firingsquad has reviewed one at 3GHz@stock and 3.5+GHz@1.525V.

hello and thanks for the input

after some browsing, i found my CPU is behaving exactly like the author of this post:
http://www.ocforums.com/showthread.php?t=498870

here are some additional E4300 info: (could we start a thread like this?)
http://www.ocforums.com/showthread.php?t=498459

seems like these week 41 OEM E4300s (aka Fry's $149 special) requires a lot more Vcore to up the speed

is it safe to run OC 24/7 with vcore at 1.5 or even, 1.55?

thanks in advance

I'm waiting for my Biostar P965 board to ship from Newegg ATM. 3Ghz is my goal. There's no way I'd feel comfortable running it at 1.525V.

im at 298 x 9 now = 2682mhz with my e4300 on an asrock dual vsta 2.40bios.

i want to go to 310mhz Fsb

My RAM runs fine at 4-4-4-12 DDR2-800, but if I set FSB to 400 and RAM to DDR2-800 and up the CPU voltage to 1.525 system doesn't POST. Any FSB holes at 400 in the Asus-P5B or do I need to up the NorthBridge voltage and RAM voltage too?

I get this exactly the same, using P5B deluxe. Seems very stsable at 333. Won't post at 340... Won't post at 400 (or 401) even if i drop the multiplier to 6.

Strange..?

 

[rookiE6400]

after some thinking, i've decided to back down to 2.83G (315x9) at 1.35 vcore (speedfan and cpu-z vocore reading = 1.33/1.32)

temperature is 44c core temp after running orthos blend for 10hrs (speedfan reads 55c), and idle temp is 24 core temp, 30 speedfan

since TAT didnt work for this E4300, i suspect core temp is inaccurate as well

from other posts, core temp and TAT is usually 10c higher than speedfan, so my guess is actual core is at 40/65 idle/orthos blend?

thinking further, if we are to "grade" these processors, OEM ones is probably a grade lower than the Retail ones.

Just got my system this week and I have it overclocked to 3.2 Ghz stable. This is with the vcore at 1.45v and vmch at 1.563v. CPU temps are 34C idle and 46C under load. Overall, I'm pretty happy with the results.

I also tried 3.35 Ghz also, but got Orthos errors so just backed it down to 3.2 Ghz.

Here are my system specs:

Asus P5N-E SLI
C2D E4300
Tuniq Tower 120
OCZ Platinum Rev 2 DDR2 800 Mhz 2 GB RAM
EVGA GeForce 7950 GT
Western Digital 500 GB HD SATA 3.0 Gbps
Antec Liberty 500W PSU

Have managed to get 3.375 game stable, but generally running mine around 3.0Ghz.

Just wondering, can anyone here hit 400MHz fsb when using these chips? I can get to 375, but it just won't get to 400, which is what I was hoping to achieve when I built my system.

- then increased to FSB 300, let it run for a few hours
- worked a few hours today, just set FSB to 385
+ i am running stable at 3.46 GHz
+ vcore 1.55V
+ temperature stays idle at 39° C, gets up to 49° on peaks
+ its a really fast PC

Nice job. Is it Orthos stable? Where'd you buy your cpu? And was it retail or OEM?

 

[MuuMuu]

AsusP5B Deluxe
OCZ Platinum DDR2-800 RAM
Scythe Ninja

Sapphire X1950XT

At 3GHz it was heating up to 65+ degrees on Orthos; most likely the heatsink isn't placed properly (i think one of the holders popped off momentarily while I was trying to wrestle the fan on there). Since I can run stable at stock voltage on 2.7Ghz I'm leaving it at that.

For what I do the heat doesn't go out of control, but is there any other reason I may want to readjust my heatsink?

 

[cnhoff]

Just had the same problems installing the Ninja...bad design :|

I will try to reseat it later.

BIOS reports 39@stock and idle. To high?

When it's too high, it don't work ..😀

 

[lookin4dlz]

Duvie, when are you going to get your e4300 & let us know ho well it oc's?

 

[cnhoff]

Have finished OC evaluation and will settle on following clocks (Orthos and dual Prime95 stable for 8 hours):

P5B-E
E4300@3.3GHz@1.45V 8x413
Scythe Ninja Rev.B
CoreTemp 27 Idle 58 Load


Btw XP and Coretemp report 3715MHz, since i lowered the multi to 8...

My 8800GTS went to 620/1000 without problems and i am currently playing Rainbow:Vegas at 1600x1200 Max and getting 30-60 frames (on some occasions it dips to 20fps though, but still playable) 😀
The GPU temps are shockingly high in comparison to the CPU temps, but that seems to be normal (fan is set to 80% duty cycle,still very quiet): 58 Idle, 73 Load

That's almost the exact same temps I get on my GTS at 650/1000 with the fan at 80%. Why does it surprise you though?? Lots of transistors (much more than NVidia 7 series) means lots of heat. I'm surprised the temperatures aren't HIGHER.

 

[cnhoff]

Because thoses semiconducotrs are all silicon based and should therefore have similar attributes when it comes to temperature. There definitely is an upper barrier.

It is rather difficult to get some hard facts on that though, because of the different methods used (BIOS, Coretemp etc.), but 80+C is definetely more than anything i have run any piece of silicon in the past.

But in the end you are right, who cares, everything is running rock solid, so... 😀

Stock Voltage Overclock
FSB: 300
Memory: 1:1
Clockspeed: 2.7Ghz

I can do 3Ghz+ easy but it requires a CPU voltage of 1.4V+ and an increase in my memor voltage. Considering that 2.7Ghz is plenty fast for me, and I can keep it all stock I'm gonna leave things here. I'm still using the original Intel cooler too. Orthos gets my CPU up to around 55-60C. I plan on upgrading to a nicer cooler soon.

 

[whovous]

This is my first Intel build since a 1.5G P4 god knows how many years ago.

Gigabyte 965P-DS3
E4300 C2D
Corsair CM2x1024 - 6400
790GS
Antec 900 case
Antec Neo 550 PSU
Zalman 8000 CPU cooler
Jing Ting Rev 2 NB cooler
Vista Home Premium

The board shipped with the F10 BIOS, but I had cold boot problems and switched to F7 and the problems have declined substantially. I may go back to F10 once I get this all sorted out, however, because it allows you to save multiple BIOS settings and F7 does not.

Right now, I am a few minutes into Orthos at 345 x 9 (3095) and CPU temps are cycling between 38 and 42C in a very cool room. Voltage is at 1.4v, and I suspect I can go lower.

The biggest problem for me right now is that whenever I choose some "bad" settings, the boot process will cycle through a few times and take a very long time to get into Windows. With the F10 BIOS, the screen would simply go bad in the same situation.

Anyway, whenever it recycles, it puts the FSB controller back on AUTO, or something like that, and the speed goes back to 200 x 9. It remembers all of my settings, so all I have to is reenable that one control.

Most of my trouble seems to be with the RAM. I have revision 5.1, and that means ProMOS instead of D9 chips. I am not 100% sure of this, but it seems that anytime I try to do anything to ask the RAM to run higher than its rated 800, even to 801, it will not boot until after it resets. Right now, I have the SPD at 2, so the RAM is only doing 345 x 2, or 690.

I've tried taking the CPU completely out of the equation by lowering its multi to 6, but so far at least, nothing I can do will let me get anything more out of the RAM. I am building this system for a friend, and will eventually dial back the settings anyway, but I would really like to get a handle on the problem here before I turn it over to him at lower, safer, settings.

Similarly, my one attempt to go 'advanced' on the RAM timings quickly reset my BIOS as well.

 

[Markfw]

well, I am close, but if 344x9 works, that will be my best. On a DS3 mobo (a tested one from Duvie) and tested memory that has run at 415, and plenty of power and cooling.

This sucker is no where as good as a 6300 IMO. If you want to use cheap memory, and don;t care about going over 2.7-3 then maybe this is your baby. If you want 3.2-3.4, you will need better memory, and a 6300 or 6400. Not a great deal, and this is not the overclocking king.

 

[whovous]

352 failed quickly at 1.375. Trying again at 1.425. Temos still very low.

 

[nyker96]

does anyone here who has both 6xxx and 4xxx can tell us if 4xxx is actually cooler running under same clocks? heard they are like 10% less heat compare to 6xxx series.
