Thread: AMD Sempron 3000+ overclock

Having read thirty thousand guides, I risked my pc overclocked. I do not want anything extreme, but not negligible. My motherboard is ga-k8vt800 with the K8T800 chipset (although I say that Sandra is the K8T800 Pro). I think that my motherboard can not lock the AGP and PCI ports. Now as much as I uploaded the fsb from 200 to 215. I have the pc running at 1.94 (previously 1.8 and the memory to 430. The problem is that going from 215 fsb the pc starts to bug me in the first test. Not to do, any thoughts or advice? I can not pass here without risking my pc? Values that I go up or down? I tried increasing voltages and neither.

The overclock synchronous, i.e. 1: 1 and memos do not support your fsb so high, you can do is leaving the memos in the bios to 166 and ht 3x in there and raise the fsb would be asynchronous. But as you say there is no port blocking for that chip, check that before, so port blocking to be more secure and you do not pass anything to your pc.

Well, not the software you holiday, if your plate K8T800 said, do not think it does not block pro .......... as it is not advisable to climb the 220 fsb. It is true that you can download the memos to prevent instability, but not by much FSB can oc with nForce3 250.............. I get to 300 fsb without problems, but that does not apply.

Thanks to both. You have many reasons. I managed to raise the fsb to 225 the ram down to 166. This is not compensated for overclocking if I’m doing. Now it's the fsb to 225 which gives me 2025 MHz and ram to 368. Is this better or worse as it was only when he raised the fsb to 215? There a way to climb over the ram?

The man now overclock the fsb to 225 you should go better than before, as I read more while FSB better, but as you say look at that if it blocks the ports that you stay in the 400 series ideal ram ...

Sometimes the slots vga suffer because of the oc, and with that you can kill, however if at any time such as unstable or can not get more try to work with voltages.

The ram stays at 368. I can not upload more going from 225 fsb me graphic, I can not lock agp. Then if you have to choose who you stay with 2025 MHz ram and 512 to 368 with the fsb to 225 or 512 and 1940 MHz ram 430con the fsb to 215?

I have the same process AMD Sempron 3000 +
I made an OC and the suicidal
HT is at 990.2
FSB is at 270
and 133-400 in the ram or anything: P
I change the OC of 1.8 Ghz@2.4Ghz

and have the ventilator produces, but it would be 2.6 or 300 fsb

I 512 (400MHz) + 128 (133Mhz) [for video sharing]

First of all, apologize for replying to an old post, but I believe that the information I provide is very good and can help many people. Comment that done in the OC-GA K8VT800 Rev2.x as has the K8T800 Pro chipset and the bios but there is no option to lock the AGP / PCI if that makes the chipset. I can not say that the trick that I will also say it works in other boards that have the same PLL (ICS 950405) if both do not have the K8T800 chipset and have the K8T800 Pro, it would be something to prove, and because the blockade does The PLL can also operate the trick.

Well the trick is to lock the AGP from modifying the byte value of 9 which by default does not block the frequencies of AGP / PCI and write the value 3F, then crashes to the 66/33 PGA / PCI with which we can make our OC motherboard and raise the FSB without concern that the rising frequency of AGP / PCI and who will not.

In the bios it is recommended to leave the HTT to 600 to raise the FSB will be around 800 (for which we Sempron) so that the top is left around 1000. Memories in my case it is DDR400 which put them in the bios latencies for 200MHz, but at 166 for seven to raise the FSB will be around 200 (actually usually a little more support, in my case 218.5 MHz), and with that without touching voltages I get to put my Sempron 3100 + at 2400MHz without any problems, and note the difference in performance. Comment I tried to raise voltages for CPU and RAM, I have also tried to see if lowering the multiplier and raising the FSB more to achieve better results, but I have been, I do not know if I may limit the Kingston Value RAM memories, the source that is generic, etc ...

The thing to do is:
1) Select the PLL "ICS 950405" to "Clock Generator Setup."
2) Select the option "Ignore GSB / PCI".
3) Click on the button "Read Clocks".
4) Click on the value of byte 09 and we will certainly another default (in my case out "4F") and where it says "Hex Value" is changed to "3F" to lock the AGP / PCI 66 / 33MHz.
5) click on the button "Update Selection".
6) Finally click on the button "Apply Selection" to apply the changes.
