I am new in the forum and I come here to share my overclocking with you of the AMD Athlon II x2 270 3400 MHz (Stock speed), and get some advise if it’s not too much to ask, please.
I could take it safely stabled up to 240, when I got to 4165 but the resulting Ht Link was below the 2000Mhz (at 1920) and I wanted to get to attain the 2000Mhz. Then I increased the overclock to the 245, that would already make an incredible increase of 45 mhz FSB for such a budget processor, but it gave a blue screen shortly after Prime95 started.
Prime gave me this in the results txt:
Cannot initialize FFT code, errcode=1005
Unable to allocate memory. One possible cause is the operating system's swap area is too small
I tried raising the Vcore slowly from 1.440 up to 1.50 but with no success and I didn’t want to go any further.
I must say that the overclock was very well stabled up to 240 bus speed, although I can’t prove with any picture of Prime95, because I went ahead to 250. But I do have the prime95 pics for the 230 where I finally left it, due to the fact that I wanted the HT link over 2000 Mhz and not below as it was the case over 233 mhz. Besides, there was no difference noticed whit the system very loaded.
And here I want o ask you a question, what would it be a better set up: 240 FSB at 4080 Mhz with HT LINK at 1920 or the actual 230 at 3910 with the HT Link at 2070? This really confuses me, since I don’t know if bein below 2000 stock is better or worse than being above up o 2100.
Said this, and as the Athlon II x2 270 has a 17 multiplier, I took it safely to 4080 Mhz Core Speed (pictures will follow, of course) and 1920 Mhz HT Link.
But, as said before due to my own choice I left it in 230 bus speed that gives me the 3910 Core Speed with 2070 Mhz of HT Link. I could get it to 232 which would give still 2088 HT Link, but I like round numbers and I decided to stay at 230.
I must say also, and I think this could be somewhat helpful for you who are reading this, that from the 200 Mhz stock bus speed up to the 230, I made the increase by a number of five, meaning 205, 210, 215 and s on. From 230 on I did the increase one by one, meaning 231,232,233, etc., except for the 250, when I passed directly from 240 to 245. I guess the blue screen has to be with memory issues, this is why I will leave here some pics for you to see how my memory timings are at this very moment.
Well, I leave you with my system specs and the pictures.
Motherboard: ASUS M5A88-V EVO
CPU: AMD Athlon II x2 270 3910 Mhz, overclocked with stock Fan
Memory:2 x 4 Gbs Kingston 1333 MHz (KVR1333D3N9)
PSU: ANTEC 650W EARTHWATTS
HDD: Hitachi IDE 320GB (I’m sure that with a SATA I could have gotten better results on the overclocking, but that will come)
Chassis fans: 4 x 120 mm (1 in the back (connected to the mobo) taking the heat out of the PC, 1 in front (for HDD)), and 2 on the left side facing the mother board, these three connected to the PSU by molex). Those 3 used as intake fans.
Could you please tell me what I am doing wrong to get this blue screen at 245. I am sure I can go well ahead of that. But I am missing something.
