OC e6300 and P5B Deluxe

[bilbrelb]

I Don't get it. I read all this hype about the 6300 OCs so well and the P5B with latest BIOS OCs it very well. So I purchase them with 1GB or Corsair XMS2 PC6400 memory (All I could afford), and I can't get squat out of this combo. If I set the FSB higher than about 275 windows starts rebooting after a while. My CPU even standard speed runs 41C Idle even after I put a thermake decent Cooler on it. (I've seen people say stock cooler will get you 2.5GHz. I wonder if these are rare exceptions to the rule.

The e6300 is unlocked down so will go 7 or 6. What good is that. I would think the $150 memory would run OCed.

I've tried increasing voltages based on many posts and the CPU gets over 50c and windows blue screens. I've locked PCI and PCIe bus speeds to standard etc..

I think OC is overrated and would have been better spending extra $40 or $100 to get better CPU and cheaper board instead of buying more $$ board to OC cheaper CPU. Plus add the extra $35 for heatsink.

Anyone had these issues and would like to help me out? SHould I have gotten faster memory? If so then it would be better to spend the extra money on faster CPU and not memory to OC.

Thanks

try cooling the NB chipset with a larger fan...

But first!!! what power supply are you using with this? What video crad are you running? have you made sure that you plugged in all the appropriate plugs to the mobo and vid card?

Considering 266 is stock if it was the cpu it should fail at 266 and you could RMA it...if it was the cpu...This would be the worst E6300 I have ever seen if it was the CPU...

Reboots at bootup are more likely power issues or ram timings out of whack..Make sure you are running specified ram voltage and set the timings to cas 5-5-5-15 to be safe out of the gate...

 

[bilbrelb]

It didn't reboot at boot up, just while playing games.
I have... (Mentioned a few of these in first post but here is the complete list for you.
Sorry about not including in first post but it was more of a frustration post

e6300
P5B - Bios dated 9/06 I believe
NV7900GT
Corsair XMS2 DDR2-800(PC6400) (Should this run at 400?)
430Watt Antec Powersupply.

Plugged in the 4 prog PS cable to motherboard beside the CPU, and the normal ATX cable.

Have two case fans and the heatsink. Plus PS has fan.
Can't remember it's cpu cooler model off hand. But it and the stock always showed about 41c during Idle not OCed which is higher than most posts.

Could someone post the exact setttings for this MB, CPU and Memory?
Thanks

Skip everything before 390FSB. In otherwords...jump right to 400Mhz FSB and memory speed DDR2-800 (1:1 ratio) that gives you 2.8Ghz.

The board does not like low overclocks but cleans up at high fsb. You can even try 425Mhz FSB and DDR2-850 (1:1 ratio) for 3.2 Ghz.

here are my settings

Jumper Free Configuration

CPU Configuration


Northbridge Configuration


Just a note make sure "Static Read Control" in the northbridge config menu is turned to disabled (not auto). It helps if you're using high FSB.

 

[bilbrelb]

Thank you for your great feedback. I will try this tonight and see where I get and let you know.

you may need more voltage to keep stability or you may be able to use less. You'll have to experiment.

Okay, welcome to the forums

Now no offense meant, but saying the P5B Deluxe is crap & that it doesn't reach over 275 only makes yourself look foolish, as that would only happen due to PEBKAC issues.

First off, as much fun as Duvie's additional NB cooling sounds, it's completely unnecessary.

As for bios settings...

Let's try to get him stable @ 275 first

But yes, avoid the 370-400 range & jump to 401+ once you get going, unless you want to fight with more tweaking.

Just to get you started, make sure you set the RAM to the 1:1 divider, or what will show as double the FSB speed.

So at stock speed, this should be FSB = 266; RAM = 533.
This is imperative if you wish to OC anywhere close to high with your components

Ensure your RAM is set to its rated vdimm

And i too would suggest manually setting the timings loose for now.
In fact, use the exact timings cmdrdredd shows in his screenshot, as they are good to start with.

I'd also recommend against using auto for the voltages, as they tend to increase drastically.
Safe voltages you can lower/increase later:
vcore - 1.4
vFSB - 1.3
vNB - 1.45
vSB - 1.5
vICH - 1.057 or auto

Now once those settings are in place, i'd try increasing FSB gradually.

Once you get to around 360, skip to 401. You may want to have vcore set to around 1.4V for this; you can always lower/increase this later to get things stable.

7x401 = 2807 MHz.

Anything past that will be dependant on your RAM OCing well

 

[bilbrelb]

Thanks fro the advice. BTW, I didn't say the board was crap, I wouldn't have bought it if I thought it was because I researched it.

I was just saying it doesn't OC like everyone says for me. I tried many of the setting but I'll try again with your suggestions and see what happens. My CPU runs hotter than many I've seen posted. Maybe thats the issue. I'm not sure but I just wanted to point out it's not always as easy as people would have you believe in the forums sometimes. And also get the help I need Been building PCs for long time and OCed mobile athlon but been awhile since I built latest since as you can tell this is upgrade from athlon

Thanks

I never even bothered to try stable at anything below 400Mhz FSB. I went to the BIOS and changed to 400Mhz the minute it posted.

 

[Alien282]

Hi, I'm using the same topic, because my parts are the same:

E6300 with the stock cooler, P5B Deluxe, 2 x 512 DDR2 800 SuperTalent, MP 7900GS

So, the situation is this:

Now I am at 1.3125 vCore (real around 1.264, according to CPU-Z), FSB running at 333 MHz, RAM 666@4-3-3-8, auto voltage. When in full load using Orthos or two Prime95s I get these readings:

CoreTemp: Core0: 59, Core1: 59.
TAT: CPU0 (I guess that's the same as Core0): 58, CPU1: 57
SensorsView: CPU: 65
PC Probe II: CPU: 65

It's pretty much the same when vCore at 1.325 (real around 1.288). So the question is this:
Which program do I trust, what is the difference between the CORE temperatures and the CPU ones? I read in another topic that CPU temps mustn't be higher than 35 or something, how come mine are 65?! Any help is appreciated!

 

[Roguestar]

Alien: those temperatures aren't too high, I wouldn't worry much about those myself personally unless you're experiencing stability problems. 35 degrees is a good target temperature but I wouldn't expect all CPUs to run at that, not under full load, without better cooling. Especially seeing as you have it overclocked anyway.


bilbrelb: post all your BIOS settings

Do you have any extra options in the BIOS turned on? Power saving, legacy USB support etc etc?

Wait a minute, my "graphics card overheating" alarm is going off. Try and get a utility program like Speedfan or CoreTemp to find out what temperature your graphics card is. If it's overheating it's a seperate problem you've got to deal with.

 

[bilbrelb]

Well, I followed the directions above and so far I'm running at 2.8ghz without any problems. Problem must have been because I was using lower FSB to start with. Weird since usually you start low and go up. Went right to 400 and 800 memory setting and it booted up fine at 2.8.

Thats good enough for me. Keep it there as good OC but not to stress cpu. Temps are about 41 idel and about 49 under full load.

I played about 1 hr of BF2 without issues so I'll see how it does.

Thanks for all the help. You've restored my faith in OCing

It's one of the little weird things about the P5B. Glad to hear you got it working.

 

[Roguestar]

I've heard it happens on quite a few motherboards. You live and learn, eh? Glad you got your game back, I'll see you on the battlefield!

 

[bilbrelb]

Well, after several days of 2.8, I was playing Titan Quest and noticed so stuttering. I went out and checked my temps. CPU was about 54c and motherboard was 45c. The Monitoring utility was complaining about MB being too hot.

I went back into the game and about 15 minutes later the whole PC just froze solid

Guess the 400MHz fsb is too much for my p5b.

I took it down to 333 it's running now at 2.3ghz ok so far. Temps on MB still high at 38 idle and cpu at 44c idle.

Think p5b could use better cooling. Since I don't have passive heatsync on CPU, I didnt hook up the fan for chipset because instructins said it woudl interfere with CPU cooling.

ANyone hook up CPU fan adn chipset fan at same time?
Thanks

 

[Pugnate]

Hey where can the divider setting be changed?

 

[n7]

Believe me, cooling is not why things are shutting down, unless you've mounted your heatsink wrong or something.

I have run with CPU temps of over 70C with no issues, as have others.

SB & NB heatsinks are scorching hot on my system, but i have no instability.

I suspect you either need more CPU vcore, mobo vcore, vdimm, or who knows what else.

If you can't pass Orthos blend, it's not the mobo's fault really, it means something's not set right.

DRAM Frequency.

 

[Pugnate]

Ahhh I see, but I am afraid to life CPU frequency over 350 and at that option I am getting weird RAM settings... stuff like 775 and 815 and stuff. I am actually a little confused.

 

[Pugnate]

So everyone is talking about going to 400FSB at default, but Anandtech kept it 350. What are the dangers of going to 400? Also what should be stable CPU and Mainboard temps?
