CPU Speed e4300

[kiria]

I want to overclock my e4300 that runs on foxconn P96557AA and 2Gb G-Skill Ram-800MHz, but the only option in BIOS I found is CPU SPEED that is adjustable from 200 to 600. So, I don't really know is this (CPU SPEED) i need to adjust, let's say up to 333Mhz, to overclock this thing? And should I manually change the DRAM timings from SPD to MANUAL and change the DRAM speed to 667 MHZ (I want to OC the CPU up to 3GHZ)?
Thanks.

The "CPU SPEED" is the FSB. Your processor's multiplier is 9. Your processors speed is FSB*Multiplier. So if you set the CPU SPEED to 200, your speed 200*9, or 1800 = 1.8 GHZ.

You're going to want to adjust the FSB slowly. Increase the FSB by 11MHz each time, then go into Windows and run Prime 95. 211x9 is going to give you 1.9GHz. Keep doing this until you reach a speed that is not stable. You never, however, just increase it from 200 to 333. A good, stable overclock is reached slowly, with a lot of testing and slowly bumping up the speed. If you do it slowly, you'll be fine and you won't hurt anything.

What memory do you have? Depending on this you may need to mess with dividers, or you could just run memory 1:1.

As long as you don't put insane voltages, I don't see the problem of immediately testing at 333mhz fsb. If you boot into windows, run orthos. If you're not stable, try 95% of your overclock (should be stable here), and then slowly increase your FSB until you're instable, then reduce about 10 mhz or so.

That's the way I've done things and the way most people seem to do it. Now, skipping up to 266x9 = 2.4GHz might be alright, but from what I've heard with the e4300's 3GHz is on the edge of instability (depends on what your CPU is like, AT's reached 3.6 others can't reach 3.0).

Alright... I'll give it to ya that 3.0GHz with stock voltage will probably be pushing it for (see sig). But I do think that he should be able to do 266*9 for 2.4GHz easily instead of wasting hours getting to that point by bumping by 11mhz and testing everytime.

You're right. However, I believe in teaching people to take baby steps with something like overclocking. If you teach someone to just throw the FSB to 266 from stock without testing anything in between, they might go crazy with other values in the BIOS as well. Such as bumping up the v-core from 1.35V to 1.5V without testing anything in between. As an overclocker, you should recognize every chip is different and just because 2400MHz is stable on your E4300 doesn't mean his will be stable. The chances of an E4300 not reaching 2.4 are slim to none, but its still not a good lesson to suddenly jump up to a high setting just because someone else with the same processor is stable.

To run my E4300 stable at 333FSB (3GHz) I need to push the voltage/heat a bit higher then I like.

300FSB (2.7GHz) @ 1.4v seems very stable.

266FSB (2.4GHz) @ 1.4v and I'm slowly trying lower voltages to see when/if it starts to fail on me.

Damn, just tried to OC it but with no success. I tried adding 11mhz each time as Extelleron suggested, the first time was ok, but when I added 22mhz, the system doesn't start up(the same for 266,300,333mhz). Tried changing vcore to 1.4, and dram vcore to 2.0, nothing happens. Changed DRAM timings to manual, set it 5 5 5 15 667 (and 800), the same black screen on monitor. All the fans are working, the cpu is working but no image on monitor, like a video card is not working. I have an pci-e16 XMS GF7900gs 256mb, that also has a power connector to my PSU. Also my PSU (500w) comes with only 4pin 12v power connector, maybe it's not enough? I'm so dissapointed, I was willing to OC this thing to 2.4ghz-3.0ghz, but I can't even get 2.0ghz (FSB 222mhz). Maybe I'm doing smth. wrong, or maybe I need to tweak smth. else in the BIOS, or some pins?!! on MB? I've read that changing pci clock to 100 helps, but I didn't find anything in the BIOS that can change PCI settings. Any suggestions?
Thanks!

 

[allies]

Make sure you set PCIE frequency to 100mhz, and then try the same stuff you've been doing. Let us know how it goes.

Edit: It should be found in the the same part where you can change FSB, DRAM timings, etc.

 

[kiria]

Things seems getting better. I didn't find pci freq settings in the BIOS, only PCI SPREAD SPECTRUM (near the CPU SPREAD SPECTRUM), have no idea what it is, but I disabled both; and Detect PCI CLK that I also Disabled. I updated the BIOS, downloaded latest utilities for the MB from the foxconn site, and they run under VISTA. When I run the utitlity to OC computer, there's a setting for the PCI freq, but it's disabled. Dunno why. I went to the BIOS, and there's a new option appeard C1E, that I disabled. Put to 266MHZ FSB, vcore to 1.38, dram vcore to 2.0, dram timimngs to 5 5 5 15 @667Mhz, and it booted!!Maybe the prob. was in the C1E that appeared in the BIOS and that I disabled?)
Run cpu-z, CPU@2.4GHz, but strange DRAM timings (5,5,5,23), freq@445mhz, dram:fsb 3:5. It seems smth. is wrong in my settings? Which timings should I put in the BIOS?

 

[kiria]

Played a little bit with it, I can't go more than 266Mhz, if I put 277Mhz - won't boot up. And I don't know really what settings should I use for the DRAM (g-skill 2gb 5 5 5 15 800mhz). And no pcie freq. settings in the BIOS (foxconn P96557AA mb), anandtech also mentioned it in theit foxconn review, but they could OC e6300 to 343mhz with no probs. May be I should put SATA drive in diff port?

Damn...
Just read the MB forum for the recommended C2D motherboards, and found this:
ATX ? Low-End
Foxconn P9657AA-8EKRS2H

Specs: P965 + ICH8R, PCIe x16/PCIe x4/PCIe x1/PCI: 1/1/1/3*, PATA/SATA/eSATA: 1/6/1, RAID, Gb LAN, ALC883, optical S/PDIF out, IEEE 1394
Overclocking: ~343MHz (E6xxx), ~265MHz (E4300)
Price: ~$108 (available only at Newegg.com)
Notes: The most feature-rich low-end ATX board

Overclocking: ~343MHz (E6xxx), ~265MHz (E4300). 265mhz for e4300. That's why I can't boot-up more than 266Mhz.
Thinking for a refund and get another board? What do you guys think of GIGABYTE GA-965P-DS3 LGA 775 Intel P965 Express ATX? Or maybe future BIOS updates could fix the 265Mhz max for e4300?

 

[RonAKA]

Do you have your RAM set to SPD or Manual? On the Memory tab of CPU-Z what do you see for Frequency and FSB-DRAM ratio?

Have you tried a bit higher voltage on the CPU? 1.4 or 1.42 or so?

Some e4300's can't reach 3.0GHz and some can reach 3.6GHz? What are "AT's"? Are there different versions of these CPU's?

 

[JeffreyY]

AT = Anandtech, referring to the one that was reviewed on this site being able to reach 3.6Ghz.

I do things exactly the opposite to the above.

But it's me who does things wrong. OP should follow this advice.

 

[Steaksauce]

I've never heard of a Core 2 Duo, let alone a e4300, clock lower than 2.7GHz.

He should be fine with going straight to 266. This isn't the socket 939 AMD, ya know.

I have the same motherboard (or close to it). It is a bit tricky to overclock with it, but I was able to finally do it. For me, the trick was to lower my starting memory speed to 533 Mhz, and then crank up the front side bus. My motherboard won't allow the memory to go anywhere above 800 Mhz, so as long as I kept it below that, I could overclock. I'm at default voltage.

I'm very happy with the Foxconn motherboard - I went through a few other one's, and this one was the most stable and had no quirks.
