Eee PC 1215n Performance

[J_lim2k2]

hi guys, has anyone of you upgraded your hdd? I just bought a new drive and I plan to change my stocked seagate that came to my 1215n. I was wondering if you need to deactivate win7 and activate it again with the new drive. how did you manage to replaced and installed yours?

You dont need to deactivate anything... all you do is install it on the new drive.

Heres a link on how to perform the swap safely:

Hey,

Today I've found couple of usefull things, about overclocking and sleep mode in 1215N.

At first, I uninstalled SuperHybridEngine, which often causes problems (when cpu overcloked, change power mode and you have beautiful crash ).

Then, I've found than ocing cpu to 2000Mhz doesn't cause any problems with sleep mode (maybe I can go higher, I'll try later). I used setfsb with -w1 -p111 parameters. So far, I haven't encountered any problems with sleep mode, booting etc. 2000-2100MHz seems to be reasonable clock for this cpu, althouh I was able to play games and run benches even on 2400Mhz, but sometimes it causes problems with WiFi.

Overclocking CPU is unpredictable - sometimes I can set 2400Mhz and it works great for whole day, but sometimes if I only set 2200Mhz I have immediate crash. Have anybody encountered things like that? I have 1215N with 2GB Hynix, I've tried also with one stick, but no difference.

Overclock is not an exact science. The problem that you described, seems to be a heat problem, or maybe something about unwanted memory overclock? Check yor memory, maybe they end up overclocked when you overclock your cpu...

The 1215n is quite a temperamental system and i very sensitive to bus speed changes. 2ghz seems to be the safe zone for overclocking this system and maintaining normal function as witnessed by yourself and others.
I dont believe it is a memory or heat issue for the simple reason that the memory is already underclocked and the system just plain doesn't get that hot.
It could be a voltage issue - pushing the boundary of stable cpu performance and it could be a pcie clock issue but it'll be hard to test either since we can't raise/lower the cpu voltage or change the pcie clock.

Same problem with the bus speed on the 1000H and n10j. You can only go so high before you cause weird problems that aren't logically connected to the CPU, unless you understand how everything interacts.

Well I geuss you can't have your cake and eat it too...

Once you've overclocked from setfsb, how do you 'unclock' or remove the clock.
besides for obviously resetting the fsb to it's original speed, but I'm assuming that that won't stop it from not turning on from sleep..

Thanks

I've never had any problems with turning on from sleep or hibernate since I removed Super Hybrid Engine. Maybe it helps

Ok, finally cpu is set to 2050Mhz (228Mhz) and it's max. 230MHz causes problems with sleep mode. I also lowered voltage in bios, still works good, but gives some more time on battery.

oogamar -> Memory isn't underclocked. Hynix sticks are 1066Mhz CL7, when normally you have 800 CL6. Raise fsb to 266MHz and you have 1066MHz CL6 and it may be too much for these standard sticks.

Actually the hynix sticks i had before i swapped to kingston were 1333mhz and as such never reached their 'advertised' speed because the bus speed simply wouldn't go that high.
Maybe underclocked was a poor choice of words but my point still stands i doubt memory is an issue. Just for reference i tried the 4gb 1333mhz ram from my m17x which overclocks really well and it made no difference.

Any progress regarding editing the BIOS to increase speed? Would it then be possible to set the modes via SHE rather than setfsb? Would things like hybernate would be no more problem then?
