Is it Bad Caps, Drivers or Your Overclock?
his essays all the useful troubleshooting of both drivers and bad caps in the Emu 1820 series of pci cards. I've had the BSODS from drivers and noise spikes and complete failure from bad caps. But follow these steps and this card is still as fantastic as anything out there. There is something special about these cards in function, dsp, glorious sound and all that I/O. Some say this Emu1820m sounds BETTER than even recent RME offerings! "StarMan" by Bowie was recorded on an 1820m as was the Moody Blue's "Tuesday Afternoon."

I've archived some research on Emu 1820m Issues below. These are saved locally because in some cases the websites have gone down.
Is it your Bad Caps or Drivers or your Overclock? For me it was Bad Caps and my Overclock, but I thought it was my driver! What a NIGHTMARE if you pick the wrong issue! If it's windows or driver problems you'll get recording failures, BSODS, crashes, freezes and such. But if you are getting funny lights or very very bad glitchy sound, that's leaning toward an overclock or bad caps.
KEEP IN MIND this: If you have lots of apps or even two that COMPETE for the resources of this card, you are asking for trouble. ESPECIALLY if one is running a 48k sound source, requiring the card to switch to that mode, and a 44.1k source or requirement. I've been running all kinds of apps at the same time though, but I do STOP the playback on unused apps. To test I'll run Kmplayer and Firefox youtube multiple videos. And it all works flawlessly. But DO NOT have a DAW such as Cubase or Reaper open while doing other video audio stuff. That's just inviting the devil into your home!
If you have glitchy, freezy, BSOD types of trouble with your Emu, go to a default factory clock speed on your CPU/Motherboard. Then if you still have issues, especially sound spikes on the Patchmix channel meters (you have to insert them on each channel strip!) You could have a redundant sound loop giving feedback (just a configuration problem) or IT IS A BAD CAP.
If your Emu is around 12 or so years old, it's probably entering bad cap territory. But with a 140watt solder gun it's a quick job to heat, pull and then reinsert the new caps.

Many uninstall their drivers for the Emu 1820 not realizing they can fix them with cap replacement. Reinstalling things CAN BE A NIGHTMARE. I hope this hasty journal helps people keep these priceless Emu alive!
I have used Reaper and various 1820m 1820 rigs with the 1820m for years on XP and then Win7 without BSODs - UNTIL I tried using the latest Win7 Beta Drivers after replacing the bad capacitors. You know, the usual two bad caps infamously blamed in many articles.

After replacing my bad capacitors and upon attempting to reinstall the Emu 1820 drivers, I encountered the "you have previously installed drivers without rebooting" error. This is a DEAD STOP for installing the PCDrv Emu driver of any kind or version. I resolved this by using "Driver Sweeper." This is NOT one of those scam apps which attempt to bilk you out of large fees for fixing "errors" they find. This is open source freeware.
Driver Sweeper was written by a music guy who was tired of manually removing Creative Drivers (they make Emu stuff) and wrote a tiny app to do this automatically. If you are uninstalling Emu drivers - USE IT. http://www.guru3d.com/content-page/guru3d-driver-sweeper.html
If you get the "you have previously installed drivers without rebooting" error, it's because there are registry entries or temp files or some kind of flag IN YOUR specific Windows USER ACCOUNT PROFILE. To get around this, create a brand new Win7 Admin User account. (it might work with another existing account, but I got tired of too much trial and error) This user profile will NOT have the flags, files or registry entries (who knows what triggers the error) which caused the "previously installed drivers" error.
When logged into this account, perhaps even from Safe Mode, run Driver Sweeper and "Check the Creative - Sound box." (It will also clean Intel, ASUS sound, Nvidia, etc). Click analyze. It will show you the remnant leftovers from the Creative installs, whether for built in sound cards or the EMU cards. Hit the clean button to remove. If it asks you to reboot, don't do it from the app. But do reboot manually. App reboots are often trouble.
I also ran the registry and file parts of CCleaner before installing. Then I was able to install whatever Emu driver I liked BUT ONLY FROM THE NEWLY CREATED user account. This install of both the Emu driver and patchmix app are universal to all user accounts so when you log back into your usual account, things will be great.
=====So which Emu Drivers Worked without BSOD on Windows 7 64x?
Using the wrong combinations of drivers meant hangs and blue screens often related to ha10kx2k.sys.
The whole post about which drivers are best and why is here:

I've posted the article and the PatchMix App and 1820m hardware Driver here: [url]http://TheGuy.com/Emu[/url]
What you want is this combo!
_00.exe + (Notice the 2-20!)
If anyone tells you to use 2.10 Patchmix with 2.20 beta driver, think twice!
EmuPMX_PCApp_L6_2_10_00.exe (wrong Patchmix version!)
EmuPMX_PCDrv_US_2_30_00_BETA.exe (Right Driver)
ver the past 2 days, I replaced TWO 1820 sets of caps. One was an 1820 non-M, the other an 1820m. The 1820 had noise spikes on first one channel, then two then all. But it would warm up and work intermittently. Now it works like new.
On the 1820m, I had HEART FAILURE. When last I used it, it was just noise spikes, like the other. But when I turned it back on just now - ALL HARDWARE inputs, save for the adats and spdif were GONE. The Patchmix said, "You don't have sufficient hardware..." That was a new and more serious error. Apparently just in storage, the caps had gotten worse...or so I thought.
What scared me was when I opened the 1820m - NO CAPS LOOKED BAD. I thought, crap, WHO KNOWS what the issue is. The typical two looked great, not even a hint of bulge or seepage. Still, I forged ahead and replaced them, just like the other.
ALL IS WORKING LIKE NEW NOW. On both units. Apparently, these two caps are THE MAJOR ISSUE and only issue, for me for the last 10 years.
John 3:19-21 This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. 20 Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. 21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."
Get Your Spiritual Armor Ready
Ephesians 6:13-18 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God. 18 And pray in the Spirit on all occasions with all kinds of prayers and requests.
Romans 8:37-39 ...in all these things we are more than conquerors through him who loved us. 38 For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
