Thread: Overclocking E6400

Hello, I recently decided to buy a new computer and I finally decided on an e6400. I told the shop I wanted a budget and quite cheap, because I simply supposed to be a core 2 duo already have a good enough performance and e6400 from the following models for little rise in the price MHz rise disproportionately. After you order it (I will bring it on Tuesday or Wednesday), I started to report on the forums a bit and everything that caught my attention is the large OC is getting people with relative ease with C2D. In principle it did not intend to OC, but seeing that everyone is doing it without any problems and I have an OC my e6400. In principle did not have anything big planned, but rather a moderate OC. Like 2.6 or 2.8 GHz would be nice. The problem is that when I asked the team had no plan to do OC then the components that I think are not the best, I think the motherboard may limit me a lot. These components are:

Core 2 Duo E6400
Board: Gigabyte ga-945p S3 s.775
1 Gb Kingston Ram 667 (2 modules of 512Mb)
Point of view 7300GT 512

My questions are:

1 - As I read almost the entire world uses the ga-965 gigabyte or asus boards, mine I have seen almost no comment on it, I have read that they had a problem you can not increase the FSB over 300 but tb lei in another forum that someone was using a 360 FSB with this board. Has anyone had experience with this board or know who may have limitations?

2 - I think the e6400 has a FSB of 266 series, so I imagine that the relationship between FSB: RAM that is by default in the bios is 4:5. If you upload the FSB to 300 and this relation would not... So what relation FSB: RAM would have to set the FSB to 300? 1:1 and losing 67 MHz of Ram?

3 - Ideally, I think it would put the FSB to 333 and so do the memory synchronous 1:1, but ... Could expand to 333 directly by the FSB without increasing voltages of anything or change anything else? How about limiting can be done without increasing voltages OC?

4 - One of the limitations that I think I can have here are the memories of 667 (the plate and accepts only those, 800 did not accept), then climb to 2.66 GHz and would have to do to OC tb reports?

5 - Another thing that worries me is that I've heard that some boards do not control the over voltage produced by the OC Ocean and also the PCI-e and can toast the chart or other component. Not be the case if my plate, but how should I put in 33 MHz frequency manually or leave it on auto? Is there more often than I have to hand it to not affect the OC?

6 - And last, I've also seen many people doing that is wrong then the OC will not start the pc and it is necessary to remove the BIOS battery for a few seconds to reset. Does this go through I can raise the FSB to 333 or more to upload? Or can only happen when the voltage is increased?

Sorry for all the questions, but I am very new to the OC and this only a few days I've been reading about it, apart from the little information that I found on my plate. And before you put hand to the new pc I needed to clarify some concepts and a little better to know what change. I hope someone can take a cable.

With regard to your questions, I will tell you that to make the chipset oc your plate is not the best. Although well supported by a C2D, the time of oc you really limited by the fsb for the support of the memos.

But I think it can reach 2664 MHz with relative ease, leaving the fsb at 333 and memos 1:1 to work on their rated speed.

Indeed memos 800 MHz will not serve as much as it only supports 667

In practice if you've seen reviews of your board in English, and have come close to the 350 MHz fsb, which would force your little memos. That should be your ceiling in terms of fsb.

If it's not a party or gets the battery or change of position for a few seconds with a jumper off the team in the manual ... it is cleaned with the bios.

Most likely, you can smoothly change the fsb to 333, without having to put anything over voltage.

Thanks for the help.

I'm eager to bring it to me. You have to be dropped now. I will first test the temperature comes up and then try to put what you say 333 FSB. 1:1 and memos. With that I would start. What if I do not like has to increase the voltage of series... In order to see if there is luck.

That ambient temperatures have?

Anyway, if you have 30 degrees cooler environments and serial may reach that temp........ but it is not advisable to pass ......... 50

The temp in any case with the 40 rounded general stock cooler, so you can check if the heat sink is good or because you change the heat sink paste.

Hi, thanks for answering.

The ambient temperature is sometimes a high in a room overlooking a courtyard, but the cause of the sudden increase of heat was forgets the Vcore manually, and then upload a The Vcore increased the fsb automatic. Now I put in 1.3 and there are no problems that increase.

OC to 2.8GHz Prescott

I wanted to ask my assistance for micro ocear is a Prescott 2.8GHz and the plate is one that leads p4s800.

So far I have raised the fsb from 133 to 148-149 to produce 3100 MHz and I can vouch that is not stable over there after suffering a few reboots and they do not run the Super PI.

Now I know what the next step, you should do something with the memories? Touch voltages? Or is it already finished what they were and that's the whole science of an Overclocked processor?

Thanks in advance to answer me.

Uploaded hitting 133 to 149, was unstable because you do not hold any memory; that is the problem you have, the frequency Download it, leave 266 and begins to raise the FSB!

They become unstable, play with Vcore increase to just watch out for fifth time.

Greetings.

Thanks for your help!

I am going to see far, but when I target voltages recommendations I would like to know that ye me, that point does not happen, in terms of climbing, and if there is anything I should know. And I also know that the memories I do not play more than the frequencies (which are already at a minimum) or do something with latencies or the divisor.

Thanks again.

To lock in those frequencies that are the default (66) PCI (33) and pci-e (100) it is more convenient to leave them locked not to burn any port of Frequency.

Greetings

The first thing we have to say if a SL7PK, SL7K9 or SL7D8? Let us put a screenshot of CPU-Z Steeping and I will tell you that you have and what you can do over the air, leaving aside other limitations of hardware it might have.

The 3.8 you do not remove anyone.

So is stepping D0 revision 4 and I remembered.

In evidence yesterday temperatures reached almost 60 ° with only the super PI I have to change the shit that comes as standard dissipates.

I just get into the BIOS and can not find the option pci; you may have to update the BIOS?

In the bios you must manually put in all values, not auto. So you can raise Vcore, vDIMM (if your ram is DDR400) must leave the speed close to 200 MHz, using dividers... regarding PCI / AGP, you should be somewhere in the bios screen. Now depend on the voltages up and tested stability.

I have not tested and these frequencies.

If you have used so well you could tell me where that option ...

Incidentally, I see that I have memories default to 2:3 ... should not put it in reverse or at least 1:1?

1:1 if there are consistent reports up the FSB ... if you have the FSB 250, the memos also go to 250 in value ram is almost a must overclock.

Added:

On the "overclocking features" part of the manual, it says fixed PCI / AGP frequency, but no locking feature in the bios. I assumed that means that it locks the frequency of the pci and as I was reading, no matter how much upload ... these frequencies are already locked "behind the scenes".
