E4300 overclocking help...

I actually asked about this in Intel CPUs a couple weeks back, but I only got one reply on it, so I wanted to double check.

To start with, I have an uncle who's been thinking of getting an E6600 for his next computer. Now, he's not much of an enthusiast, but I'm thinking he might appreciate the $170 Canadian he's save (based on local prices) by o/cing a e4300 to E6600 speeds. He's lose the extra L2 cache, but I would think that's not going to be a major issue.

Now, the way I understand this, this simply requires bumping the FSB from 800 to 1066... something I should be able to do while leaving motherboard warrenty intact, since it's a speed the boards already have to support. In addition, I shouldn't need to overclock the memory and therefore will retain the warrenty on that part. I'll just lose the CPU warrenty. Is this assumption correct?

Also, I was wondering if the stock cooler is sufficient for this or if I need something stronger, since I'd like to try and keep as much of that $170 difference as possible (to be saved towards future upgrades and the like.
 
Dont quote me on this, but I'm sure I read that 2.6Ghz can be reached on a e4300 with stock cooling, just by rising the FSB alone.

Using an Artic Cooling Freezer Pro 7 I have clocked mine to 3.0Ghz by just rising the FSB. I tested it with two instances of Orthos running for an hour and it was stable, I haven't tested it for longer yet. And my temps are good. I seem to have hit a wall there, but I haven't played with the voltages. To be honest though, I'm pretty pleased with that result.
 
You'll be fine with the stock cooler up to about 3ghz.

Sorta... But maybe not exactly, depending on what board you're using. When you say "800" that value is quad pumped... So your starting value will be either 800 or 200, depending on how your BIOS chooses to report FSB. The stock FSB for an e4300 is 200mhz, but as I said, it might be reported as it's "quad pumped" value, of 800 (200 x 4).

Raising your FSB from 200 (800) to 300 (1200) should be fairly possible with an aftermarket cooler like the AC freezer Pro mentionned above.

In addition, I shouldn't need to overclock the memory and therefore will retain the warrenty on that part. I'll just lose the CPU warrenty. Is this assumption correct?

Once again, depends on the board. Any non 680i or 650i board has the RAM linked with the FSB, so raising the FSB speed raises the RAM speed too. It's possible that you, might have to OC the ram a little. Intel won't know you've OC'd your processor (assuming you don't DESTROY it from heat or voltage) so while you'd technically void the warranty, they'd never know.

NCIX.com has an E6400 for just over 200$ with a 9% price cut for the next week, which could easily get to 3.2-3.4ghz with the AC freezer listed above.
 
I have a biostar 965PT, e4300, g skill ddr800 (1gbx2) 5x5x5x15 (1.8-2.0 v), 550W PS, and Artic Cooler 7

Now, I must be the biggest moron, but I cannot overclock this damn CPU. People say they just raise the FSB and bingo... well, not with my stuff...the following is my BIOS manual set up:

Overclock Navigator Engine set to Manual Overclock

CPU Voltage: 1.4
FSB T Voltage: Default (1.2)
MCH Voltage: Default (1.8)
Memory Voltage: 2.1
System Memory Freq: Default (Auto) ** You can choose 533 667 800
CPU Clock: 233Mhz ** default is 200Mhz
PCIE Clock: Default (Auto) ** default at 100
DRAM Conf: Default (Set by Spd) 5x5x5x15
TWR: Auto TWTR: Auto TRRD: Auto TRTP: Auto


what the hell am i doing wrong?
 
System Memory Freq: Default (Auto) ** You can choose 533 667 800

PCIE Clock: Default (Auto) ** default at 100

Set the RAM frequency to 553

Set the PCIe clock to 101mhz


That's your problem.

WHAT IS WRONG WITH THIS?

Overclock Navigator Engine set to Manual Overclock (BIOS 965PT)

CPU Voltage: 1.4
FSB T Voltage: 1.2
MCH Voltage: 1.8
Memory Voltage: 2.2
System Memory Freq: 533 ** Only settings are 533 667 800
CPU Clock: 255
PCIE Clock: 101
DRAM Conf: 4x4x4x12
TWR: Auto TWTR: Auto TRRD: Auto TRTP: Auto


BOLD = Changes made

Details: I'm not sure if I have to make any changes to TWR, TWTR, TRD, and TRTP. Honestly, I don't know what that does. I have followed SEVERAL instructions from people here, but I can't seem to go over 255 FSB. Yes, I have tried 401 since some people said the Biostar is "notorious" for not working between 250-400 or something like that.

Personally, I think there was WAY TOO MUCH HYPE about this CPU and it really does not perform as "easy" as most people who originally posted reviews said. At this point, I don't know what to do. Running at 2.3-2.4 on a 1.8 Core 2 Duo is not the greatest, but it's better than nothing. I would love to know where the REAL BIOSTAR 965PT overclockers are??? :p
 
I am also having trouble OC'ing my E4300. I was having getting anything between 2.7-2.8ghz, but when I jumped the FSB to 333 @ 3.0ghz it booted and right now its been stable in orthos and occt for 3 hours and going. I have the voltage set at 1.45, but I notice in CPUid it reads only 1.40 or 1.41 :confused:
 
DRAM Conf: 4x4x4x12


Try setting these to 5-5-5-15.

Thats the last thing I can think of...
